Abstract
In this work, multi-walled carbon nanotubes (MWCNTs) were successfully enwrapped by a thin layer of phthalocyanine copper (CuPc) via solvent-thermal method to obtain the core-shell CuPc@MWCNTs hybrid materials, which were confirmed by SEM and TGA characterization. The optical spectroscopy including FTIR and UV–vis were used for probing the surface chemical modification of MWCNTs. Thereafter, CuPc@MWCNTs/polyarylene nitrile ethers (PEN) composite films were prepared via solution-casting method. Based on the SEM and rheological characterization of polymer composites, CuPc@MWCNTs hybrid materials show good dispersion and compatibility in the PEN polymer matrix, leading to the excellent thermal, mechanical and dielectric properties.
