Sol‐gel derived hybrid aerogel monoliths and coatings of methyltrimethoxysilane (MTMS) and glycidoxypropyltrimethoxysilane (GPTMS) are prepared sucessfully. MTMS/GPTMS is hydrolyzed under acidic conditions and further condensed under basic conditions to generate a gel network followed by a sequential solvent exchange process and ambient drying to obtain aerogel monoliths. The as‐synthesized alcogel is homogenized in methanol and coatings are fabricated on glass substrates by dip coating method followed by controlled thermal treatment at 400 °C to get organically modified silica (ORMOSIL) based aerogel coatings. The transparent ORMOSIL aerogel coating made from the composition of MTMS/GPTMS ratio 1: 0.5 is found to be highly porous with an average pore size of ∼100 nm and hydrophobic coatings with water contact angle of ∼100 ° are obtained. The hybrid aerogel has ∼334 m²g⁻¹ surface area (BET) with an average pore diameter of ∼2.7 nm, and the coating retains its hydrophobicity even after thermal treatment at 400 °C. Hybrid aerogel coatings were also made on cotton canvas fabrics which demonstrate oil adsorption‐desorption properties and is a viable remedy for oil‐spill cleanup.

透明和疏水的MTMS / GPTMS混合气凝胶整料和涂层的溶胶-凝胶法：溢油清除的可行解决方案

成功制备了溶胶凝胶衍生的混合气凝胶整体料和甲基三甲氧基硅烷（MTMS）和环氧丙氧基丙基三甲氧基硅烷（GPTMS）的涂层。MTMS / GPTMS在酸性条件下水解，然后在碱性条件下进一步冷凝，生成凝胶网络，然后依次进行溶剂交换过程和环境干燥，以获得气凝胶单块。将合成后的醇凝胶在甲醇中均质化，然后通过浸涂法在玻璃基材上制备涂层，然后在400°C下进行受控热处理，从而获得基于有机改性二氧化硅（ORMOSIL）的气凝胶涂层。发现由MTMS / GPTMS的比例为1：0.5的组成制成的透明ORMOSIL气凝胶涂层具有很高的多孔性，平均孔径约为100 nm，并且获得了水接触角约为100°的疏水涂层。² g ^-1表面积（BET），平均孔径约为2.7 nm，即使在400°C热处理后，涂层仍保持疏水性。混合气凝胶涂料还可以在棉帆布织物上制成，这些涂层具有油吸附-解吸特性，是清除溢油的可行方法。
