The effects of oxygen plasma treatment on tensile deformation of nano-SiO2 sol-gel coating ultra-high molecular weight polyethyleneUHMWPE filaments are investigated and a new concept for the nano-structural interface between fiber surface and nano-coating is provided. The tensile test results show that the activation volumes of UHMWPE filaments untreated and treated with oxygen plasma ranging from 1718.448 to 16603.070 nm3 by using Eyrings equation are an important description of the properties of the nano-structural interface between fiber surface and nano-coating, in addition to the enhanced ductility of UHMWPE filaments after nano-SiO2 sol-gel coating UHMWPE filaments treated by oxygen plasma. From the results of scanning electron microscope and Fourier transform infrared spectroscopy, it is observed that the uniform dispersion of the nano-SiO2 coating on the UHMWPE filaments treated by oxygen-plasma not only fills in the micro-flaws, but also introduces the activated functional groups into the fiber surfaces.
