This paper presents novel organic–inorganic (hybrid) nanocomposite coatings (EASFs) containing a diamino diphenyl sulfone (DDS)-based structure with fluorine chains and SiO₂ networks. To obtain these nanocomposites, a diamino diphenyl sulfone (DDS)-based structure (SFDDS) containing silane terminated fluorine chains was synthesized. This structure was converted to a novel precursor (SFDDS precursor) by adding hydrolyzed tetraethoxysilane (TEOS) and trimethylsiloxy propyl methacrylate (MEMO) by the sol–gel method. This way, SFDDS precursor was obtained and incorporated into a mixture of epoxy acrylate and 1,6-hexanediol diacrylate reactive resin system in the range of 2.5–15%. The prepared solutions were spread onto low-carbon steel with a 75 μm wire-wound applicator instrument and cured by UV light. These coating samples were characterized in terms of their thermal, wear, physical, and corrosion properties. Considering physical properties, while hydrophobicity and scratch resistance presented substantial increases, adhesion and brightness properties decreased. The adhesion properties of EASF10 and EASF12.5 were fairly good, but their wear resistance values showed decreases at these adhesion levels. Glass transition temperatures increased with an increase in the SFDDS precursor content. This situation showed that these novel hybrid nanocomposite coatings could have higher thermo-mechanical properties. Besides these results, the corrosion resistance values of these novel hybrid nanocomposite coating materials were noteworthy. While the corrosion resistance results of these novel coatings were enhanced substantially in the air atmosphere, the NaCl atmosphere adversely affected corrosion resistance.

具有含氟二氧化硅网络的新型紫外固化纳米复合杂化涂层的磨损、热、腐蚀和物理性能

本文提出了新型有机-无机（杂化）纳米复合涂层（EASF），其含有二氨基二苯砜（DDS）基结构，具有氟链和SiO ₂网络。为了获得这些纳米复合材料，合成了含有硅烷封端氟链的二氨基二苯砜（DDS）基结构（SFDDS）。通过溶胶-凝胶法添加水解四乙氧基硅烷（TEOS）和甲基丙烯酸三甲基硅氧基丙酯（MEMO），将该结构转化为新型前体（SFDDS前体）。通过这种方式，获得了 SFDDS 前体，并将其掺入环氧丙烯酸酯和 1,6-己二醇二丙烯酸酯反应性树脂体系的混合物中，含量范围为 2.5-15%。使用 75 μm 绕线涂抹器将制备的溶液涂抹到低碳钢上，并通过紫外线固化。这些涂层样品的特征在于其热性能、磨损性能、物理性能和腐蚀性能。就物理性能而言，疏水性和耐刮擦性大幅提高，但附着力和亮度性能下降。EASF10和EASF12.5的粘附性能相当好，但它们的耐磨性值在这些粘附水平下表现出下降。玻璃化转变温度随着 SFDDS 前体含量的增加而增加。这种情况表明这些新型杂化纳米复合涂层可以具有更高的热机械性能。除了这些结果之外，这些新型杂化纳米复合涂层材料的耐腐蚀性值也值得注意。虽然这些新型涂层的耐腐蚀性能在空气气氛中显着增强，但氯化钠气氛却对耐腐蚀性产生了不利影响。
