Commercially feasible self-cleaning surfaces are highly desirable for various technological applications. However, the current approaches are challenging to scale up and often lack the desirable performance. The synthesis of novel siloxane-based additives for the oversimple fabrication of surfaces with excellent self-cleaning properties is reported herein. These siloxane-based additives are synthesized by the free-radical polymerization of methacryloxypropyl-terminated polydimethylsiloxane (PDMS) with tetrahydrofurfuryl acrylate (THFA) monomer at various compositions, and these additives were subsequently incorporated into UV curable coatings. In total, four novel additives and 16 different compositions are evaluated in this study for their water, oil, and hexadecane repellent properties, as well as for their anti-ink performance. The surface roughness and textures of these coatings are characterized via atomic force microscopy (AFM) analysis and scanning electron microscopy (SEM), while X-ray photoelectron spectroscopy (XPS) was employed to map the surface chemical compositions of these coatings.

商业上可行的自清洁表面非常适合各种技术应用。然而，目前的方法难以扩大规模，而且往往缺乏理想的性能。本文报道了新型硅氧烷基添加剂的合成，用于简单地制造具有优异自清洁性能的表面。这些基于硅氧烷的添加剂是通过甲基丙烯酰氧基丙基封端的聚二甲基硅氧烷 (PDMS) 与丙烯酸四氢糠酯 (THFA) 单体以各种组成进行自由基聚合合成的，这些添加剂随后被加入到紫外线固化涂料中。在这项研究中，总共评估了四种新型添加剂和 16 种不同组合物的防水、防油和十六烷排斥特性，以及它们的抗油墨性能。
