Title: Electrical and optical properties of nitrile rubber modified by ion implantation

Implantation of N{sup +} ion beams are performed on to a non-conjugated elastomer, acrylonirtle butadiene rubber (NBR) with energy 60 keV in the fluence range of 10{sup 14} to 10{sup 16} ions/cm{sup 2}. A decrease in the resistivity of the sample by about eight orders of magnitude is observed in the implanted samples along with color changes. The ion exposed specimens were characterized by means of UV/Vis spectroscopy which shows a shift in the absorption edge value for the as deposited polymer towards higher wavelengths. The band gap is evaluated from the absorption spectra and is found to decrease with increasing fluence. This study can possibly throw light on ion induced changes in the polymer surface.
