Inventor of VaSC - a platform technology to create bio-inspired architectures Developed a novel fabrication route toward the fabrication of industry scale microvascular composites (as long as one meter) via a sacrificial fiber method Performed screening process on catalysts that efficiently decrease the depolymerization temperature of poly(lactic acid) fibers Discovered a catalytic reaction system that improved the reaction rate of PLA depolymerization from 1wt%/hr to 25wt%/hr, considerably shortening the manufacture time from 100 hours to less than 4 hours Optimized chemical treatment process to produce sacrificial PLA fibers that can be readily used in VaSC technique Improved in-house extrusion of catalyst enriched PLA fibers from lab-scale production to industry-scale production with yield up to 380 yards/day Designed SOP for large-scale production of PLA sheets via hot press technique Successfully demonstrated applications of microvascular materials, including self-healing composite, autonomous cooling panel, anti-inflammatory pad, fluorescent keyboard protector, etc. Studied phase separation behavior in biphasic polymer membranes Fabricated an active membrane as a high temperature-safe lithium-ion battery separator using PLA as a porogen

Probed into self-assembly of polymeric systems. Multi-responsive micelles are obtained via host-guest interactions between two molecular recognizing groups. The synthetic strategy and self-assembly behavior of multi-responsive micellization might represent a promising new direction in the field of macromolecular design and synthesis, which may find practical applications in areas such as drug delivery and smart release.

Discovered a new approach to prepare stimuli-responsive hyperbranched polymers–via a combination of ATRP and click reaction, which is easier, more convenient and has a wider range of potential applications compared to the traditional approaches. It's a successful attempt to introduce “Click Chemistry” to polymer synthesis and might even go on to provide a template for synthesizing hyperbranched polymers. Successfully synthesized silver composite nanoparticles based on these hyperbranched polymers which can be categorized as inorganic-organic hybrid functional material
