Systematic study was carried out to characterize the effects of Nitrogen ion plasma on nano composite polymer membrane. Using solution casting and spin coating method, nano composite polymeric membranes in the range of 20 micron were prepared. Nitrogen ion plasma treatment was done for these membranes. Variable treatment time was used to modify the membrane surface and its characteristics. These membranes were characterized before plasma treatment and after plasma to make comparative study by different technique such as AFM, UV-Vis Spectrometry and Fourier transform infrared spectroscopy. Results show the Plasma treatment is a quite effective tool for improving the properties of composite membranes with unique characteristics. These results are discussed in this paper.

Nano particles of silver has been synthesized by Mangifera indica (mango) plant extract and characterized using UV-Vis spectrophotometer, FTIR (Fourier Transform Infrared Spectroscopy), XRD (X-ray Diffraction) and SEM (Scanning electron microscope). These nanoparticles were used as nano composites for polymer membranes. Using solution casting and spin coating method, Ag nano composite polymeric membranes in the range of 20–40 micron were prepared. Helium ion glow discharge plasma treatment was done for the membranes. Surface modifications for membranes were characterized before and after plasma to make comparative study by different technique such as optical microscopy, SEM- Scanning electron microscope. Results are discussed in this paper.
