这项研究介绍了合成方法来开发疏水表面。疏水表面通过无机-有机杂化物的交联来制造，所述无机-有机杂化物由双臂烷氧基硅烷官能化的氨基甲酸酯前体（AFUS）制备。无机-有机（I-O）杂化物是通过各种前体的共水解和共缩合来合成的。然后将混合溶液用于通过旋涂方法制备疏水涂层。涂层表现出大于90°的水接触角。用扫描电镜（SEM）和接触角测定仪（CA）对涂层的性能进行了分析和表征。采用傅里叶变换红外光谱（FT-IR）、热重-差热分析（TG-DTA）和凝胶渗透色谱（GPC）对前驱体进行了表征。这些环境友好的无机-有机杂化涂料在取代有毒的氟化烷基硅烷基涂料方面显示出巨大的潜力。
This study introduces synthetic methodology to develop hydrophobic surfaces. Hydrophobic surfaces are fabricated via cross-linking of inorganic-organic hybrids, prepared from dipodal alkoxysilane-functionalized urethane precursors (AFUS). The inorganic-organic (I-O) hybrids are synthesized by co-hydrolysis and co-condensation of various precursors. The hybrid solutions are then used to fabricate hydrophobic coatings through spin coating method. The coatings exhibited water contact angle greater than 90°. The properties of the hydrophobic coatings are analysed and characterized using scanning electron microscopy (SEM) and contact angle measurement (CA). The precursors are characterized by Fourier transform infrared spectroscopy (FT-IR), thermogravimetric-differential thermal analysis (TG-DTA) and gel permeation chromatography (GPC). These environment-friendly inorganic-organic hybrid coatings have shown great potential in replacing the toxic fluorinated alkylsilane based coatings.
