摘要:

首先在超高分子量聚乙烯(PE⁃UHMW)纤维表面形成聚多巴胺涂层,再通过水热法在纤维表面原位生长ZnO纳米阵列。对聚乙烯亚胺(PEI)介导的合成体系ZnO长径比、改性前后PE⁃UHMW纤维的界面性能进行了研究,并揭示了其增强机理。结果表明,ZnO纳米阵列的生长并未对纤维的热稳定性及结晶度产生影响,对纤维的损伤较小;当PEI浓度为3 mmol时,ZnO长径比最高;改性后纤维界面黏结强力提升了63.6 %,层间剪切强度提升了70.14 %。

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 method. 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 interfacial bond strength and interlaminar shear strength of the fibers were enhanced by 63.6 % and 70.14 %, respectively, after the modification.

Key words: ultra?high molecular?weight polyethylene fiber, surface modification, polydopamine, zinc oxide nano?array
