Effect of Technology of Modification of Polymer-piezoceramic Composites on their Pyroelectric Properties

Abstract

UDC 541.64:537.228.1

 

Under investigation have been pyroelectric properties of polymer-pyroelectric ceramic composites whose components had been previously modified by the electric discharge plasma effect, as well as pyroelectric properties of composites crystallized under the simultaneous action of the barrier discharge plasma and temperature. Plasma crystallization of composites is shown to be a more effective technology with the view of imprevement of pyroelectric properties. By plasma crystallization a high and stable pyroelectric state is formed in case of the formation of the local level phase in the quasi-gap of the polymer, with the activation energy being higher than deorientation energy of composite pyrophase domains.

 

Keywords: polymer composites, pyroelectric ceramic, barrier discharge plasma, plasma crystallization.
