摘要

制作功能性彩色憎水表面对许多工业应用都非常重要。在此,我们使用活性哈洛石纳米管负载染料(A-Hal/dye)、不同的烷氧基硅烷(甲基三乙氧基硅烷(MTES)、辛基三乙氧基硅烷(OTES)和十六烷基三甲氧基硅烷(HDTMS)),制备了各种具有憎水性能、耐化学腐蚀、耐热、耐紫外线和自清洁性能的彩色表面涂层材料、OTES)和十六烷基三甲氧基硅烷(HDTMS))以及四乙氧基硅烷,并将它们涂覆在各种基底上,以确定涂覆配方中使用的烷氧基硅烷化合物的烷基链长度对多彩表面的表面特性的影响。使用电子显微镜(TEM 和 SEM)、SEM 制图、傅里叶变换红外光谱、XRD、XPS 和热重力分析技术对合成表面或涂层材料进行了表征研究。发现涂有 A-Hal/MB/MTES、A-Hal/MB/OTES 和 A-Hal/MB/HDTMS 材料的玻璃表面的水接触角(WCA)分别为 148.0、156.2 和 159.3°。在涂层配方中使用具有长功能烷基链基团的烷氧基硅烷化合物提高了表面的憎水性,但略微削弱了着色表面的机械稳定性。在多彩表面涂上聚二甲基硅氧烷(PDMS)涂层后,涂层的机械稳定性、热稳定性、化学稳定性和环境稳定性都得到了改善,但涂覆多彩表面的憎水性却有所下降。制备的不同颜色的涂层材料被成功用于涂覆玻璃、滤纸、木材和棉织物等各种基材。研究结果表明,制备的 A-Hal/dye/HDTMS 涂层材料在功能性表面涂层的制备中具有很大的潜力。

Design and characterization of multicolor water-repellent coatings: Impact of alkyl chain length on surface properties
Fabrication of functional colored water-repellent surfaces is very important for many industrial applications. Here, various colorful surface coating materials having water repellent property, chemical, thermal and UV light resistance and self-cleaning property were prepared using activated halloysite nanotube loaded with dye (A-Hal/dye), different alkoxysilanes (methyltriethoxysilane (MTES), octyltriethoxysilane (OTES) and hexadecyltrimethoxysilane (HDTMS)), and tetraethoxysilane and their coatings were performed on various substrates to determine the effect of alkyl chain length of alkoxysilane compound used in the coating formulation on the surface properties of colorful surfaces. Characterization studies of the synthesized surfaces or coated materials were performed using electron microscopy (TEM and SEM), SEM-mapping, FTIR, XRD, XPS and thermal gravimetic analysis techniques. Water contact angle (WCA) of glass surfaces coated with A-Hal/MB/MTES, A-Hal/MB/OTES and A-Hal/MB/HDTMS materials was found to be 148.0, 156.2 and 159.3°, respectively. The use of an alkoxysilane compound with long functional alkyl chain group in the coating formulation improved the water-repellent property of surface, while it slightly weakened the mechanical stability of the colorful surface. Polydimethylsiloxane (PDMS) coating, which were applied on colorful surfaces, improved the mechanical, thermal, chemical and environmental stability of coating, but decreased the water-repellent property of coated colorful surfaces. Fabricated coating materials having different colors were successfully used to coat various substrates such as glass, filter paper, wood, and cotton fabric. The results of this study show that A-Hal/dye/HDTMS coating materials prepared here are of a great potential in the fabrication of functional surface coatings.
