Dr Jinglei Yang is currently an Associate Professor of the Department of Mechanical and Aerospace Engineering at the Hong Kong University of Science and Technology (HKUST). Prior to joining HKUST, he was an Assistant Professor at Nanyang Technological University (NTU) and a Post-doctoral Research Associate at University of Illinois at Urbana-Champaign (UIUC). He obtained his Bachelor and Master degrees from University of Science and Technology of China in 1999 and 2002, respectively, and Ph.D. degree from the Institute for Composite Materials at Technical University of Kaiserslautern, Germany in 2006. He received Wilfried Ensinger Award supported by the Scientific Alliance of the University Professors of Polymer Technology (WAK) Germany for his excellent PhD dissertation work. His research interests include multifunctional composites/structures/coatings and mechanics. He has held a number of grants as Principle Investigator with total support of equivalent CNY22 million including governmental and industrial projects. He has done significant research and innovation work in his areas and filed a number of international patents and published more than 80 refereed papers (with citation of >2000 and H-index of 21) in the high impact journals. He often gave Keynote and invited talks in the important international conferences and acted as board member and peer reviewer by invitation for a number of scientific journals.

Abstract

Encapsulation techniques have been developed since last century primarily for controlled release or slow release in various areas, including pharmacy, food technology, cosmetics, etc. The encapsulated product, namely microcapsule, has a core-shell structure. By tuning shell structures with desired core materials, a vast number of combinations of new microcapsules can be designed and fabricated to realize unusual or unconventional functions that a single material cannot fit. Therefore, in the last two decades, functional and multifunctional intelligent materials based on microencapsulation have been successfully designed and developed for potential engineering applications. In this talk, I will introduce and review various encapsulation techniques developed in my group to fabricate different types of microcapsules for multifunctional materials, which have addressed specific engineering issues, such as self-healing of damage, self-cleaning surface coatings, anti-fouling marine coatings, encapsulated phase change materials for green buildings, self-lubrication of tribomaterials, encapsulated shear-thickening liquids for impact resistance, and so on. The perspectives of future development of microencapsulation methods will be commented as well.
