IMPROVEMENT OF POLYMER SURFACE LAYER BY ELECTRON RADIATION

Abstract

This article deals with improving properties of the surface layer of varying polymer products. The surface layer of the tested polymer was influenced by electron radiation with varying intensity. This resulted in improved resistance to wear due to the creation of a 3D network within the polymer structure. The properties were measured by an instrumented test using a contemporary ultra-nano indentation device. The acquired data was then evaluated by OLIVER & PHARR method. Irradiation of surface layer caused a 16 % (26 %) improvement of mechanical properties in comparison to the unaltered material.
