Abstract Organic-inorganic hybrid coatings were developed via a sol-gel method using hexagonal boron nitride (h-BN) as a ceramic filler material incorporated into a polymeric matrix. To investigate the effects of h-BN on the properties of polymer-based coatings, parameters such as hardness, coefficient of friction, and hydrophobicity were investigated. Colloidal silica (CS), methyltrimethoxysilane (MTMS), water, and acid catalyst containing coatings were prepared by varying the content of h-BN from 10% to 25%. All the coatings were prepared with the same experimental procedure and coated on 1050 aluminum alloy plates. The compensating contents of MTMS and colloidal silica with a fixed molar ratio of MTMS and CS were set to be 1:1.2, and a specific amount of the catalyst was utilized. Coatings were examined by Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), and energy-dispersive X-ray spectroscopy (EDS). The most promising physical properties were determined to be the pencil hardness of 8B, adhesion strength of 5B, coefficient of friction of 0.332 N, and water contact angle of 114.75°. Therefore, it can be concluded that the h-BN improves the physical properties of polymeric coatings. In addition, this study demonstrates the effect of h-BN on the adherence of polymer matrix-based hybrid coatings.

六方氮化硼对金属表面涂层用有机-无机杂化聚合物薄膜摩擦系数的影响

摘要 有机-无机杂化涂层是通过溶胶-凝胶方法开发的，使用六方氮化硼 (h-BN) 作为陶瓷填充材料并入聚合物基体中。为了研究 h-BN 对聚合物基涂层性能的影响，研究了硬度、摩擦系数和疏水性等参数。胶体二氧化硅 (CS)、甲基三甲氧基硅烷 (MTMS)、水和含酸催化剂的涂层是通过将 h-BN 的含量从 10% 改变到 25% 来制备的。所有涂层均采用相同的实验程序制备并涂覆在1050铝合金板上。固定MTMS和CS摩尔比的MTMS和胶体二氧化硅的补偿含量设置为1:1.2，并使用特定量的催化剂。通过傅里叶变换红外光谱 (FTIR)、扫描电子显微镜 (SEM) 和能量色散 X 射线光谱 (EDS) 检查涂层。最有希望的物理性能被确定为铅笔硬度为 8B，附着强度为 5B，摩擦系数为 0.332 N，水接触角为 114.75°。因此，可以得出结论，h-BN 改善了聚合物涂层的物理性能。此外，这项研究证明了 h-BN 对基于聚合物基体的混合涂层的附着力的影响。可以得出结论，h-BN 改善了聚合物涂层的物理性能。此外，这项研究证明了 h-BN 对基于聚合物基体的混合涂层的附着力的影响。可以得出结论，h-BN 改善了聚合物涂层的物理性能。此外，这项研究证明了 h-BN 对基于聚合物基体的混合涂层的附着力的影响。
