UHMWPE, infrared spectroscopy, Raman spectroscopy, polymer crystallinity, cross-linking, oxidation


We systematically used infrared (IR) and Raman spectroscopy to study the structure of unprocessed and perturbed UHMWPE by ?-irradiation. We tested the proposed methods on selected polymer samples with known structure. We used vibrational spectroscopy to analyse the chemical structure of two different types of UHMWPE with different molecular weight and density under the trade names GUR 1020 and GUR 1050. The samples were exposed to four different doses of g-irradiation, which induces the cross-linking and oxidation of polyethylene chains. The showed results proved that vibration spectroscopy can be a fast, efficient, non-destructive and simple tool to characterize the oxidation and degree of crystallinity of UHMWPE, while the accuracy of determining the degree of cross-linking was omitted by the process of oxidation and band overlapping.
