摘要

摘要本研究采用空气等离子体和ZnO涂层对超高分子量聚乙烯纤维(UHMWPE)进行改性。用电子扫描显微镜(SEM)观察了涂覆和未涂覆ZnO纤维的表面形貌，并用x射线能谱分析了表面化学成分。测试了纤维的抗冲击性能和热失重(TGA)。本研究结果表明，O- c =O基团的吸附增强了纤维表面的化学活性，从而增加了纳米zno涂层与纤维表面的结合力。在纤维表面发现了致密的网状纳米氧化锌涂层。经等离子体预处理的纤维可获得更完整的涂层，处理120 s后热稳定性提高19.7%，处理90 s后抗冲击性能显著提高177%。图形抽象

Air Plasma-Nano ZnO Coating Improves the Impact Resistance of Ultra-High Molecular Weight Polyethylene Fiber

ABSTRACT In this study, air plasma and ZnO coating was used to modify ultra-high-molecular-weight polyethylene fibre (UHMWPE). The surface morphologies of the fibre with and without ZnO coating were examined under an electron scanning microscope (SEM), and the surface chemical composition was studied through X-ray spectroscopy. Moreover, the impact resistance and weight loss heat weight (TGA) of the fibre were examined. The results of this study indicated that the chemical activity of the fibre surface was enhanced due to the adsorption of O-C=O group, thus increasing the binding force between nano-ZnO coating and the fibre surface. A compact net-like nano-ZnO coating was identified on the fibre surface. The fibre pre-treated by plasma can be plated with more complete coatings, the thermal stability was enhanced by 19.7% after 120 s of treatment, and the impact resistance was significantly increased by 177% after 90 s of treatment.
