Hydrophilic polypyrrole (PPy) thin films were deposited by simple Successive
Ionic Layer Adsorption and Reaction (SILAR) method on glass and stainless steel substrate
from aqueous solution. The structural and optical properties were studied by means of X-ray
diffraction (XRD), Fourier transforms infrared (FTIR) spectroscopy, and Fourier transforms
Raman (FT-Raman) Spectroscopy and UVVIS spectrophotometer. The surface wettability
properties were studied by means of Contact angle meter. The results showed the SILAR
method allows the formation of amorphous and hydrophilic polypyrrole thin films. The
polypyrrole thin film showed contact angle of in the range of θc = 30 deg. to
θc = 48 deg. The
calculated value of surface tension varies between 11.68 mN/m and 19.60 mN/m. Also, the
values for work of adhesions were calculated.
