Abstract
A technique is proposed for obtaining electroconductive, mechanically strong, and elastic composite material based on polypyrrole and hydrophilized polyethylene. The relationship is established between the process parameters and properties of the composite material such as electroconductivity and mechanical strength. Several methods are considered in the view of increasing electroconductivity of the material. Physical and mechanical properties of the composite material are investigated.
Highlights
Polypyrrole (PPy) is a typical electroconductive polymer from the class of the unique materials which combine metallic and semiconductor properties with such polymeric characteristics as flexibility, strength, and elasticity
The synthesis of composite PE-polyacrylic acid (PAA)-PPy consisted of two stages: postradiation graft polymerization of acrylic acid onto PE film, and polymerization of pyrrole in the bulk and on the surface of PE film modified with PAA
In this work a technique is proposed for obtaining three-component composite materials on the basis of PE substrate modified with grafted PAA and PPy
Summary
Polypyrrole (PPy) is a typical electroconductive polymer from the class of the unique materials which combine metallic and semiconductor properties with such polymeric characteristics as flexibility, strength, and elasticity. Polypyrrole is obtained in the form of black powder by monomer oxidation [2]. By far it is the most extensively studied conducting polymer since a pyrrole monomer is an oxidized, water-soluble, commercially available material that possesses environmental stability, good redox properties and high electrical conductivity [3]. Some factors currently limiting the applications of PPy include its poor mechanical strength and low processibility [5]. Single-component materials on the basis of PPy are characterized by extremely low mechanical properties and fragility
