To prepare conducting polymer composites, porous polymethyl methacrylate (PMMA) particles with di โ erent speciรc surface areas were prepared by seeded emulsion polymerization and solvent extraction. The dried porous particles were imbibed with the oxidant solution and adsorbed pyrrole from a solutio

โฆ Synopsis
Structural changes proceeding in composites under the effect of various mechanical deformations (stretching, compression, shear, etc.) affect the structure of an electrical conducting system. Mechanical stresses, induced by deformation of composite materials during deformation, affect both the molecular and supermolecular structure of polymers. As a consequence, they also affect a substructure bound to it and composed of filler particles. It is evident that in the case of conducting polymer composites, mechanical deformations should reflect electric conductivity of materials.
