报告人简介:Costas S. Patrickios received his Ph.D. degree in 1994 from the Department of Chemical Engineering (Thesis advisor Professor T. Alan Hatton) at the Massachusetts Institute of Technology (MIT) in Cambridge, USA. His doctoral studies were followed by post-doctoral work at the University of Sussex, UK, under Professors S. P. Armes and N. C. Billingham (1994-1995). His first academic position was in the Department of Chemical Engineering at the University of Manchester Institute of Science and Technology (UMIST) also in the UK (1996-1997). He then (1998) moved to the Department of Chemistry at the University of Cyprus, and became full professor in 2007.
His research involves the synthesis, characterization and modeling of well-defined, amphiphilic polymer co-networks.
报告摘要:This lecture will provide an overview of our work on the development of mechanically-robust [1], self-healable [1,2] and self-assembling [3] amphiphilic polymer co-networks [4] via the use of model building blocks interconnected through chemically reversible cross-links. Four-arm star polymers with aldehyde or acylhydrazide groups, were used to form dynamic covalent acylhydrazone cross-links, resulting in hydrogels with the properties of self-healing, reversibility, recyclability and injectability. Amphiphilicity is introduced into the co-networks to lead to self-assembly in aqueous media, with the formed hydrophobic domains promoting solubilization of hydrophobic species (drugs for delivery or environmental pollutants for sequestration), and providing a means for mechanical energy dissipation, thereby further enhancing the mechanical properties of the system. Potential applications of such gel polymer electrolytes as the membrane separator in lithium ion batteries will be discussed.
