December 2021 Jixiong recently published another two papers on thermal transport in polymer and polymer composites:
1. Molecular dynamics simulation of thermal transport in semicrystallline polyethylene: Roles of strain and the crystalline-amorphous interphase region, journal of applied physics, 130, 225101, 2021. [We analyzed the thermal transport in the interphase region and revealed the importance of chain topologies in the interlamellar region]
