Effects of oxygen plasma treatment on microstructure and tensile deformation of Nano SiO2 coating Kevlar filaments

Original Kevlar filaments and nano SiO2 coating Kevlar filaments treated with APPJ with helium as the carrier gas and oxygen as the treatment gas, respectively. From the SEM micrographs, an increase in surface roughness and the decrease of fibrillation degree after helium and oxygen plasma treatment could be observed. Contact angle analysis showed the treated Kevlar filament had lower contact angle than the untreated one. Based on FTIR results, the change of wet ability and surface energy is attributable to the polar groups on the fiber surface introduced by the treatments. Further, specialized tensile testing at different strain rates ranging from 0.01 s-1 to 0.6 s-1 were conducted at room temperature, revealing the different treatments on Kevlar filaments suggest the change rate sensitivity. And a nonlinear constitutive equation was established to estimate activation volumes (nano-scale).
