Synthesis and High Dielectric Properties of Poly(aryl ether ketone)/Phthalocyanine

摘要

@@High dielectric constant polymers with excellent electric properties, proper mechanical strength, and good processing properties are of great importance for applications such as super capacitors, on-chip capacitors, and electromechanical devices including artificial muscles, smart skins for drag reduction,and microelectromechanical systems. However, for one-component systems, it is hard to realize all these properties. Conventional polymers are easy to process but generally suffer from a low dielectric constant (less than 10). In the past several decades, the composite approach, in which high dielectric constant particulates (most of which are ferroelectric ceramics) were added to a polymer matrix, has been employed to raise the dielectric constant of polymer based materials. However, because ceramic materials have an elastic modulus much higher than that of polymers, the increased dielectric constant comes at the cost of losing flexibility and significant increase of the elastic modulus.
