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.
