Study on dielectric properties of polypyrrole coated fabrics

Flexible polypyrrole coated cotton fabric and polypyrrole coated nylon fabric with good dielectric property was produced using pyrrole as monomer by in-situ polymerization on cotton fabric and nylon. The influence of the type and concentration of dopants on the dielectric property and surface resistance were discussed. The results showed that dopants have great influence on the dielectric property and surface resistance of polypyrrole coated cotton fabric and polypyrrole coated nylon fabric. The produced polypyrrole/cotton composite materials and polypyrrole coated nylon fabric show excellent dielectric property and conductivity. This study laid solid foundation of developing more practical multi-function absorbing composite materials.
