The purpose of this study is to investigate the influence of vitamin E (D, L-α-Tocopherol: VE) on microscopic deformation behaviour of UHMWPE. UHMWPE sample with 3wt% VE (3%VE) showed dispersed negative-strain area and also showed an elevation in Ic values indicating crystallinity after applying 30% tensile road. It is likely that molecular chains tend to reorient with deformation and the reorient sites tend to show the low area strain with the low Ic values. Considering that 3%VE had the negative area strain and the Ic values elevation, We hypothesized that the VE addition had the possibility to contribute to the molecular chains mobility and the reorientation which result in the increase of negative-strain area and the elevation of Ic values when tensile strain was applied.
