Improvement of polymer surface layer by electron radiation

This article deals with improving properties of surface layer of varying polymer products. Surface layer of the tested polymer was influenced by electron radiation with varying intensity. This resulted in improved resistance to wear due to creation of 3D network within the polymer structure. The properties were measured by instrumented test using a contemporary ultranano 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.
