Abstract
The polypyrrole/polyaniline composite thin films were prepared by a simple electrodepositon technique on stainless steel substrate. The FT-IR spectra confirm the formation of polypyrrole/polyaniline composite structure; the surface morphology showed that polypyrrole/polyaniline has cauliflower like structure in 90-10% composite whereas there is drastic change in morphology in the 50-50% composite. The microwave properties such as reflection, absorption, dielectric behavior of polypyrrole/polyaniline composite thin films with frequency were studied in the frequency range 13-18Â GHz. The thickness, DC and microwave conductivity were also studied. The dielectric constant and microwave conductivity showed higher value in the 70-30% composite thin film.
