Effect of polymeric additives on the formation and properties of polyaniline films on polyester fabrics

Electrically conductive films based on polyaniline (PANI) and polyethylene glycol (PEG) molecules of different chain length were synthesized on polyester textiles (PET) through in situ polymerization. Fabric supports were placed in the monomer bath in the presence of polymeric additive firstly and t...

Description
Summary:Electrically conductive films based on polyaniline (PANI) and polyethylene glycol (PEG) molecules of different chain length were synthesized on polyester textiles (PET) through in situ polymerization. Fabric supports were placed in the monomer bath in the presence of polymeric additive firstly and then immersed into the oxidant solution to initiate the reaction. Influence of the PEG segment length on monomer adsorption process toward fabrics was investigated by comparing the adsorption thermodynamic parameters. The polymeric layers' morphologies have been evaluated using the field emission scanning electron microscope, and the film formation mechanism has been investigated. Compositions of the films synthesized in the absence and presence of PEG were characterized by attenuated total reflection Fourier transform infrared. The electrical resistance measurement results indicated that the electrical conductivity of PET/PANI-PEG composite fabrics decreases slowly as the PEG segments length increased, and the thermal stability was improved slightly according to thermogravimetric analysis values.
