Speakers

Prof. Yanchun HAN received her B. S. degree from University of Science and Technology of China (USTC) in 1990 and Ph. D. degree from Changchun Institute of Applied Chemistry (CIAC), Chinese Academy of Sciences (CAS) in 1995. From 1996-2000, she worked as a postdoc/visiting scholar at University of Naples, University of Kaiserslautern (Alexander von Humboldt Research Fellow) and University of Michigan. She joined the State Key Lab of Polymer Physics and Chemistry, CIAC as a full professor in 2000. She is the Senior Editor of POLYMER and in the editorial board of ACS Applied Materials & Interfaces, Polymer Chemistry, Polymer Crystallization, Chinese Journal of Polymer Science and Giant. Her current research interests include polymer thin films and inherent structure–property–processing relations of conjugated polymers.

Control over Solution Phase Structure and Thin Film Morphology for High Performance Conjugated Polymers

Abstract

Conjugated polymers have attracted much attention for their (opto)electronic and biomedical applications. The solid-state properties of conjugated polymers depend sensitively on their morphologies across all length scales. This multiscale morphology in the solid state is largely affected by solution-state aggregates and their assembly pathways from solution to thin films. In this talk, I will address two issues, 1) how to control the precise solution-aggregate structures by changing the strength of attractive interactions between segments and 2) how the solid-state morphology and electronic and mechanical properties can be determined by solution-phase structure and assembly pathways in a controllable fashion.
