主 题:Lectures on Modern Approaches to the Physics and PhysicalChemistry of Soft Matter主讲人:Prof. Kenneth S. Schweizer (University of Illinois at Urbana-Champaign)地 点:华南软物质科学与技术高等研究院(北区科技园2号楼)324报告厅第一讲 Glassy Dynamics and Kinetic Arrest in Soft Matter and Materials Science时 间:2018年11月7日(周三)10:00(Pedagogical Introduction)和15:00(Research Seminar)第二讲 Dynamics and Viscoelasticity of Entangled Synthetic and Biological Polymer Liquids时 间:2018年11月8日(周四)10:00(Pedagogical Introduction)和15:00(Research Seminar)第三讲 Structure, Phase Behavior, Dynamics and Mechanical Response in Polymer Nanocomposites时 间:2018年11月9日(周五)10:00(Pedagogical Introduction)和15:00(Research Seminar)材料科学与工程学院华南软物质科学与技术高等研究院2018年10月29日第1讲内容简介:Understanding of the spectacular slowing down of relaxation and mass transport in glass-forming liquids of atoms, molecules, colloids, nanoparticles, polymers and other materials over 14 or more orders of magnitude remains a grand challenge. Moreover, many advanced materials employ amorphous solids, and vitrification can frustrate the assembly of ordered structures. In the first talk, I will present an introductory overview of glassy dynamics from the liquid side describing both the qualitative similarities and large quantitative differences between material classes and even within a single class of compounds (e.g., polymers). The physical ideas, assumptions and limitations of both venerable phenomenological models and more modern approaches will be discussed. In the second talk, I will present our new microscopic, force-based predictive theoretical approach to activated relaxation and emergent elasticity that can address both the physical and chemical aspects of glassy dynamics and kinetic arrest for molecular, colloidal and polymeric systems over the entire range of relevant temperatures and relaxation times. Its generalization to thin films will be briefly mentioned, followed by an in depth discussion of the technologically important problem of penetrant diffusion in supercooled liquids and glasses. Quantitative confrontation of our theories with experiments will be presented throughout the talk. Finally, limitations of our approach and key open questions will be discussed.第2讲内容简介:The existence and dynamical consequences of topological entanglements between strongly interpenetrating and sufficiently large and/or dense macromolecules of diverse architectures (chains, rods, star-branched) is a fascinating and unique phenomenon in polymer science which is also highly relevant to cell biology. Its fundamental origin is the emergent kinetic consequences of polymer connectivity and uncrossability. In the first talk, I will give an introductory overview of the key features of entangled dynamics, viscoelastic response and diffusion from an experimental perspective. Classic models of unentangled and entangled linear chain and rigid rod liquids will then be described and their predictions compared with experiment. Though existing theories in equilibrium have had many successes, they are highly phenomenological and there remain multiple open fundamental issues especially under strong deformation conditions crucial to polymer processing and internal force mediated processes in biopolymer networks. In the second talk I will present an overview of our recent theoretical work that aims to develop a first principles, force-based, predictive statistical dynamical theory for the quiescent (under isotropic, oriented and confined conditions) and nonequilibrium (strained, stressed) behavior of entangled flexible chain and rigid rod liquids. New predictions will be described from a physical perspective along with quantitative comparisons with experiment and simulation. Open and difficult questions in the area of nonlinear rheology will be briefly discussed, and our recent ideas for making progress sketched.第3讲内容简介:Polymer nanocomposites (PNC) are typically hybrid organic-inorganic materials that traditionally have combined rigid nanoparticles (diameters 5-200 nm) and flexible macromolecules to achieve unique properties. The classic example is rubber reinforcement via filler particles which is of central importance in the tire industry. However, the field has largely been empirically driven. Over the past decade or two, major progress has been made at formulating and addressing fundamental physical questions concerning these multi-component materials which involve an exceptionally broad range of time, length and energy scales. In the first talk, I will present an overview of the general PNC problem and selected recent contributions by experimentalists, simulators and theorists that address mainly the question of phase behavior and microstructure as a function of chemical and physical variables, and its impact on dynamical properties. In the second talk, I will give an overview of our theoretical efforts over the last decade which have aimed to merge and extend ideas and methods from colloid and polymer physics and physical chemistry to create new predictive and microscopic statistical mechanical theories that address PNC multi-scale structure, states of aggregation, phase separation, nanoparticle diffusion, glass and gel formation, and how nanoparticles modify polymer entanglement phenomena. The new physical ideas will be described along with model calculations and quantitative comparisons with x-ray and neutron scattering, diffusion, structural relaxation, and mechanical measurements.主讲人简介:Ken Schweizer received a B.S. in physics from Drexel University in Philadelphia, and a Ph.D. in physics from the University of Illinois at Urbana-Champaign (UIUC) in 1981 working with the theoretical physical chemist David Chandler. After a postdoc in chemical physics at Bell Labs with Frank Stillinger, in 1983 he joined the Materials Directorate at Sandia National Laboratories where he learned about polymer and materials science. In 1991 he moved to UIUC where he is presently the G. Ronald and Margaret H. Morris Professor of Materials Science and Engineering, Professor of Chemistry, Professor of Chemical and Biomolecular Engineering, and member of the Frederick Seitz Materials Research Laboratory and the Beckman Institute for Advanced Science and Technology. His research interests are centered on developing, and applying to experiment, predictive microscopic statistical mechanical theories of the structure, thermodynamics, phase behavior, dynamics and rheology of diverse soft materials including molecules, polymers, colloids and nanocomposites in the liquid, suspension, crystal, liquid crystalline, thin film, rubber, gel and glass states. Honors include the Dillon Medal, Polymer Physics Prize, and Fellowship from the American Physical Society, the Joel Henry Hildebrand Award in the Theoretical and Experimental Chemistry of Liquids from the American Chemical Society, and the Drucker Eminent Faculty Award and undergraduate and graduate teaching excellence and student mentorship awards from UIUC.附件:无

报告摘要:

Klaus Müllen (克劳斯米伦)教授博士毕业于瑞士巴塞尔大学化学系,为德国科学院院士,美国艺术与科学院外籍院士,美国化学会志 (J. Am. Chem. Soc.) 第一位外籍副主编。研究方向:石墨烯等碳材料,功能染料和颜料,新型合成方法学,有机金属化学,具有复杂空间构象的新型高分子,共轭聚合物,液晶材料,有机光电器件,生物合成材料、复杂大分子,纳米复合材料。

Incredible progress has been made in synthetic polymer chemistry to control the polymer chain length, structure and architecture via controlled/living polymerization reactions as well as their functionalization via efficient post-modification chemistries. The development in this field is still very intense and dynamic, leading to an ever-increasing molecular complexity.

Klaus Müllen joined the Max Planck Society in 1989 as one of the directors of the Max Planck Institute for Polymer Research. His PhD degree was granted by the University of Basel in 1972. He received his habilitation in 1977 at ETH, Zürich. In 1979 he became a Professor at the University of Cologne, and in 1983 at the Johannes-Gutenberg-University, Mainz. He owns about 60 patents, published over 1700 papers and has an h-index of 136.

However, this increasing complexity on the molecular level demands for highly advanced specialists possessing the skillset to synthesize such chemical structures. This clearly limits or slows down the advancement to new scientific areas. Hence, we have addressed this challenge over the years by developing simple synthetic routes, while maintaining a molecular complexity, thereby providing the synthetic tools for many scientists to prepare highly functional polymer materials with unprecedented molecular precision.

Klaus Müllen's broad research interests range from the development of new polymer-forming reactions, including methods of organometallic chemistry, to the chemistry and physics of small molecules, graphenes, dendrimers and biosynthetic hybrids. His work further encompasses the formation of multi-dimensional polymers with complex shape-persistent architectures, nanocomposites, and molecular materials with liquid crystalline properties for electronic and optoelectronic devices.

Synthetic routes, possibilities, remaining challenges and opportunities for next generation polymers will be discussed with the aim to development and study of structure-property relationships of polymeric materials. As such, novel syntheses of polymer materials for smart materials and battery related materials will be presented as examples.
