研讨会：Nanoengineered Polymer Materials: Preparation and Application

活动详情

活动简介

We initiated polymer nanoresearch in the early 1990s, focusing on developing diverse nanostructure preparation methods. We delved into the captivating physical and chemical properties of these nanostructures, while also exploring their potential applications. This lecture outlines the inception and progression of our research, highlights overarching strategies for crafting block copolymer nanostructures, and presents use cases for nanostructured block and graft copolymers. Specifically, I will discuss the use of fabric modified with block copolymer monolayers for the rapid and efficient separation of oil from emulsions. I will also report on the creation of effective self-cleaning and ice-shedding coatings from graft copolymer self-assembly. Notably, one of our recent coatings demonstrates hardness levels nearly ten times greater than that of widely utilized poly(ethylene terephthalate). While this coating maintains its structural integrity even after enduring hundreds of steel wool abrasions, its ice adhesion strength is just 1/10,000th of that of glass.
