摘　　要：通过静电作用和范德华力制备六方氮化硼@聚多巴胺@3-氨基丙基三乙氧基硅烷(h-BN@PDA@APTES)复合材料,使用傅里叶变换红外光谱(FTIR)、X射线衍射(XRD)和扫描电子显微镜(SEM)等方法对其结构进行表征.制备的h-BN@PDA@APTES掺杂环氧(EP)粉末涂料(m-h-BN/EP),并进行形貌分析、热重分析(TGA)、中性盐雾测试、电击穿强度测试和体积电阻率测试,研究h-BN@PDA@APTES对EP粉末涂料的影响.与传统EP粉末涂料相比,m-h-BN/EP粉末涂料的绝缘和耐腐蚀性显著提高,焦残渣增加12.0%,电击穿强度提高69%,体积电阻率提高19.2倍.实验结果表明,经改性的h-BN在粉末涂料中具有良好的应用前景.In this work,hexagonal boron nitride@polydopamine@3-aminopropyl-triethoxysilane(h-BN@PDA@APTES)composites were prepared by electrostatic interaction and van der Waals forces,and their structures were characterized using Fourier transform infrared spectroscopy(FTIR),X-ray powder diffraction(XRD)and scanning electron microscopy(SEM).The novel h-BN@PDA@APTES doped epoxy(EP)powder coating(m-h-BN/EP)was prepared for the first time.The effect of h-BN@PDA@APTES on EP powder coating was investigated by means of performance tests such as morphological analysis,thermogravimetric analysis(TGA),salt spray resistance test,electrical breakdown strength test and volume resistivity test.Compared with traditional EP powder coating,m-h-BN/EP powder coating showed significantly higher insulation and corrosion resistance.The char residue increased by 12.0%,the dielectric breakdown strength increased by 69%,and the volume resistivities improved by 19.2 times.Experiment results show that modified h-BN has good promising applications in powder coating.
