  • Title: Nanoengineered Polymer Materials: Preparation and Application


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.


Guojun Liu received his Ph.D. from the University of Toronto in 1989. He joined the University of Calgary as an assistant professor in 1990 and was promoted to full professor in 1999. Since 2004, he has been serving as Tier I Canada Research Chair in Materials Science in the Department of Chemistry at Queen's University. Between 1993 and 2012, he led the development of nano- and microstructured materials constructed from block and graft copolymers. Since 2012, his research has focused on the creation of various novel nanostructured polymer materials and exploring their applications. He is the inventor of the anti-smudge and ice-shedding NP-GLIDE coatings. He has published more than 240 journal articles and authored more than 10 patents. In 1999, he was granted the National Natural Science Overseas Outstanding Young Investigator Award of China. In 2007, he received the Polymer Science and Engineering Award from the Chemical Society of Canada and was selected as a Leading Talent in Guangdong Province in 2010. He is a Fellow of the Royal Society of Canada.
