Abstract
In this work, novel nanocomposite films formed from polyarylene ether nitrile (PEN), barium titanate (BaTiO3), and multiwalled carbon nanotubes (MWCNTs) were successfully prepared by the solution casting method combined with continuous ultrasonic dispersion technology. The micromorphology, thermal, mechanical, and dielectric properties of the nanocomposite films are investigated. All of the nanocomposite films exhibited excellent thermal stability and mechanical strength almost the same as pure PEN film. Their initial decomposition temperatures were up to 492°C, and the tensile strength was over 82 MPa. Besides, the nanocomposite films had excellent flexibility, as the films could be curled easily into cylinders with several layers. Furthermore, it was found that the film with 1.5 wt.% MWCNTs and 20 wt.% BaTiO3 had the best comprehensive dielectric properties, with potential for application in organic film capacitors.
