基于艾琳方程,提出用于定量分析纤维表面和纳米涂覆层间的纳米界面结构的理论模型.实验结果表明,纤维高分子链段受力塑性变形时,纳米界面结构内纳米微粒阻碍其形貌变化产生热激活体积,该热激活体积是纳米界面结构性能的重要表征;氧等离子体处理对纳米二氧化硅溶胶涂覆高强、高模聚乙烯纤维有增韧作用.由不同处理样品的扫描电子显微镜图片和傅里叶变换红外光谱曲线对比分析可知,经氧等离子体处理纳米二氧化硅溶胶涂覆高强、高模聚乙烯纤维的纳米涂覆层纳米颗粒分布均匀,纳米颗粒还填补纤维表面微观缺陷,活性官能团被引入到纤维表面.
Based on the Irene equation, a theoretical model for the quantitative analysis of the nanostructured interfacial structure between the fiber surface and the nano-coating was proposed.The experimental results show that the nano-particles in the nanostructured interfacial structure block the shape The thermal activation volume is an important characterization of the nanostructured interfacial properties. Oxygen plasma treatment toughens the nanosilica sol coated high-strength, high-modulus polyethylene fibers. The scanning electron microscopy Comparing the results of Fourier transform infrared spectroscopy (FTIR) and Fourier transform infrared spectroscopy (FTIR), we can see that nanoparticles coated with nanosilica sol coated by oxygen plasma were uniform in the nano - coating of high - strength and high - modulus polyethylene fibers. Nanoparticles also filled the micro - Functional groups are introduced to the fiber surface.
