Effect of ultra-low content of graphene filler on the thermooxidative and tribooxidative properties of composite materials based on ultra high molecular weight polyethylene
Abstract
The thermooxidative and tribooxidative properties of UHMWPE/graphene composites with an ultra-low graphene content are studied. Composites were prepared by in situ polymerization with a filler content of 0.014 to 0.05% by weight. The introduction of graphene into UHMWPE leads to a significant improvement in tribo-oxidative properties, but it practically does not affect on thermal oxidation. This is explained by various oxidation mechanisms that are implemented in the process of thermal oxidation and tribooxidation in the composite.
