Abstract

Molecular orientation in ultra high molecular weight polyethylene (UHMWPE) when it is subjected to wear is important in understanding the basic wear processes for this material. Current methods of inferring or deducing orientation information for UHMWPE lack surface sensitivity and mostly rely on staining the specimens followed by SEM examination (1). Our objective is to use the electric field polarization dependence of soft x-ray absorption to determine if molecular orientation at surface layer immediately after rubbing can be measured for UHMWPE.
