When polymer film or polymeric polymer composite films were exposed to electron radiation they undergo chain
scission or crosslinking according to their different physical parameter. For radiation scission and crosslinking are two opposite
consequences. The effect of electron radiation on the surface microhardness of PI and PI+ITO+GO polymeric composite thin
films was studied to understand and analyze the radiation-induced crosslinking and radiational scissioning. The Carl Zeiss NU2
Universal research microscope was used to measure study the surface microhardness of the radiated films. The value of Hv
is found to be higher for polymeric composite radiated films.
