Piezo-active composite systems based on porous polyvinylidene fluoride films and conducting polymer layers as electrodes

The study has obtained composite systems containing porous polyvinylidene fluoride films and electroconducting polymers—polyaniline polypyrrole. Porous supports were prepared by melt extrusion. It was shown scanning electron atomic force microscopy that PVDF have a relief surface, higher surface roughness improves hydrophilicity of supports. layers conducting polymers on the formed oxidative polymerization in situ monomer solution. found coatings high adhesion to due film. Composites volume conductivity order 101 S/cm 10–6–10–5 S/cm, respectively. used as electrodes polarize composites measure piezomodulus d31. maximum value d31 18 pC/N.
