文摘

Ultra-high molecular weight polyethylene (UHMWPE)/disilanolisobutyl polyhedral oligomeric silsesquioxane (POSS) nanocomposites in a disentangled state were synthesized by in situ ethylene polymerization. This is the first report of a detailed study on the phase structure and mechanical properties of disentangled UHMWPE/ POSS nanocomposites in a solid state. The phase structure and chain dynamics of UHMWPE nanocomposites were characterized using wide-line proton NMR and 13C cross-polarization/magic-angle spinning (CP/MAS) solid-state nuclear magnetic resonance (NMR). The results showed that a strong interaction between the POSS and nascent UHMWPE matrix occurred in a solid state, especially in the intermediate and monoclinic crystalline phases. This strong interaction between POSS particles and UHMWPE chains may result in improved melt recovery properties. Mechanical testing indicated that the lowest friction coefficients and highest breaking strength were achieved when 1 wt% loading of POSS was incorporated. The influence of the microstructure on lubrication and mechanical properties was also studied.
