Abstract This study is aimed to develop UV-curable hybrid sol–gel coating in order to improve the surface properties of polystyrene (PS) against chemical degradation problem. First, hybrid sol-gels were synthesized using TEOS, VTMS, C2H5OH, distilled water, 1 M HCl, 1 M NH4OH, TiO2 and inorganic (Al2O3, SnO2, ZrO2) and organic (Tetrahydrofuran (THF)-C4H8O) chemicals. Second, the synthesized hybrid sol-gels were coated on the surface of PS plates using an applicator and pre-treated at −80 °C for 24 h and the coated plates were cured under UV light at 40 °C for 1 h. The original PS plates and coated PS plates were subjected to a yellowing test for 26 h. Third, colour (CM-2600d. Konica Minolta Optics Inc. Japan) and gloss (Multi Gloss 268 Plus. Konica Minolta Optics Inc. Japan) measurements, hardness (TroniC–Hildebrand Shore D), FT-IR (Perkin Elmer Spectrum 100 model FTIR spectrometer), SEM (SEM-ZEISS Supra 40 V P), TGA (TGA, Setaram Labsysevo model), AFM (AEP-Nanomap-500LS) and contact angle (KSV0 CAM 200) analyses of the original and UV-cured hybrid sol gel-coated PS plates were performed before and after the yellowing test. As a result, it was observed that the surface properties of the PS plates coated with the hybrid sol-gel prepared using C4H8O organic compound of 0.5 g improved significantly.

用溶胶-凝胶法在聚苯乙烯上制备抗黄变紫外光固化复合涂料

摘要 本研究旨在开发可紫外光固化的混合溶胶-凝胶涂层，以改善聚苯乙烯 (PS) 的表面性能以应对化学降解问题。首先，使用 TEOS、VTMS、C2H5OH、蒸馏水、1M HCl、1M NH4OH、TiO2 和无机（Al2O3、SnO2、ZrO2）和有机（四氢呋喃 (THF)-C4H8O）化学品合成混合溶胶-凝胶。其次，使用涂抹器将合成的混合溶胶-凝胶涂覆在 PS 板的表面上，并在 -80°C 下预处理 24 小时，然后将涂覆的板在 40°C 的紫外线下固化 1 小时。原始的 PS 板和涂覆的 PS 板进行 26 小时的泛黄测试。三、颜色（CM-2600d. Konica Minolta Optics Inc. Japan）和光泽度（Multi Gloss 268 Plus. Konica Minolta Optics Inc. Japan）测量，硬度（TroniC–Hildebrand Shore D），FT-IR（Perkin Elmer Spectrum 100 型 FTIR 光谱仪）、SEM（SEM-ZEISS Supra 40 VP）、TGA（TGA、Setaram Labsysevo 型）、AFM（AEP-Nanomap-500LS）和接触角（KSV0 CAM 200）分析原始和UV固化混合溶胶凝胶涂层PS板在黄变测试之前和之后进行。结果，观察到涂有使用0.5g C4H8O有机化合物制备的混合溶胶-凝胶的PS版的表面性质显着改善。
