Facile synthesis of copper phthalocyanine supported on MWCNTs to improve their dispersibility and compatibility in PEN matrix

A novel multi-wall carbon nanotubes-copper phthalocyanine (MWCNTs-CuPc) hybrid material was successfully prepared from 1, 3, 5-tri-(3, 4-dicyanophenoxy) benzene (TPh) and CuCl through a simple and effective solvent-thermal route. FTIR, SEM and TEM results display that the convex surfaces of MWCNTs were successfully coaxially coated by self-assembly organic functional materials. This can effectively prevent MWCNTs from agglomeration, and also can greatly improve their dispersibility and compatibility in polyarylene ether nitriles (PEN) matrix through intermolecular interaction. Most importantly, the permittivity of the nanocomposite film is as high as 55 at 100 Hz when the mass fraction of CuPc-MWCNTs reaches 5.0 wt%.
