超高分子量聚乙烯纤维表面纳米ZnO可控生长及其界面性能研究
Controllable growth and interfacial properties of ZnO nanoparticles on surface of ultra-high molecular-weight polyethylene fiber
摘要
Abstract
A polydopamine coating was first formed on the surface of ultra-high molecular-weight polyethylene(PE-UHMW)fibers,followed by an in-situ growth of ZnO nano-arrays grown on the fiber surface using a hydrothermal meth-od.The aspect ratio of ZnO obtained from the PEI-mediated synthesis and the interfacial properties of PE-UHMW fibers before and after modification were investigated,and the enhancement mechanism was revealed.The results indicated that the growth of ZnO nano-arrays did not affect the thermal stability and crystallinity of the fibers,and there was less damage to the fibers.The system obtained the highest aspect ratio of ZnO at a PEI concentration of 3 mmol/mL.The in-terfacial bond strength and interlaminar shear strength of the fibers were enhanced by 63.6%and 70.14%,respective-ly,after the modification.关键词
