1Liquid crystalline texture and hydrogen bond on the thermal conductivities of intrinsic thermal conductive polymer films显示文摘Polymer-dispersed liquid crystal(PDLC)films comprising polyvinyl alcohol(PVA)and liquid crystal monomer(LCM)were successfully obtained by the method of solution casting&thermal compressing.LCM was distributed orderly in PVA matrix by hydrogen bond interaction,to form PVA-LCM interpe net rating-layered networks.When the mass fraction of LCM was up to 35 wt%,the corresponding in-plane thermal conductivity coefficient(λ//)of PDLC film was significantly increased to 1.41 W m^(-1)K^(-1),about 10.8 times that of neat PVA(0.13 W m^(-1)K^(-1)).High intrinsicλ//values of PDLC films were mainly attributed to the formed microscopic-ordered structures from ordered stacking of LCM,ordered arrangement of PVA chains,and their hydrogen bond interaction.This work would offer a new way to design and prepare novel intrinsic high thermal conductive polymers.Ying Li Changdan Gong Chenggong Li Kunpeng Ruan Chao Liu Huan Liu Junwei Gu 2021Journal of Materials Science & Technology2021,,23:2
