Preparation and thermal conductivity of copper phthalocyanine grafted boron nitride nanosheets
2018
Abstract Copper phthalocyanine grafted boron nitride nano-sheet hybrids (CuPc- g -BN) were prepared for the improvement of thermal conductivity of CuPc. Hydroxyl functionalized BN (BN-OH), obtained by ball-milling of BN, was reacted with isophorone diisocyanate (IPDI) and 3-aminophenoxyphthalonitrile (3-APN) sequentially to form BN-IPDI-CN. CuPc- g -BN was prepared by in-situ polymerization of BN-IPDI-CN with 1,3,5-tri-(3,4-dicyanophenoxy) benzene (TPh) and CuCl. The CuPc- g -BN and the intermediates were characterized by TEM, AFM, XPS, FTIR and UV–vis. The results show the formation of the hybrid effectively enhances the thermal conductivity of CuPc, which is as high as 0.63 W/(m·K), with an increment of 290%, when the mass fraction of BN-IPDI-CN is 50 wt%.
