Surface modification of PC-TiO2 nanocomposite film by LF O2 plasma

In this work, polycarbonate and polycarbonate-TiO2 nanocomposite film were prepared. Initiallypolycarbonate was dissolved in dichloromethane. Then TiO2 nanoparticles were added to the solution. The effect of LFO2 plasma (50 Hz) on the hydrophilicity, surface morphology of polycarbonate and polycarbonate-TiO2 nanocompositehas been studied. The structural of samples were studied by X-ray diffraction and FTIR analysis. Surface properties ofpolycarbonate and polycarbonate–TiO2 nanocomposite films were studied by contact angle measurement and atomicforce microscopy (AFM). The water contact angle significantly decreased from 90° to 56° after plasma treated.
