我们提出了一类新的超疏水表面由低成本和容易合成的氧化铝纳米粒子功能化羧酸具有高支链烃（HC）链。这些支链是新的低表面能材料（lsem），可以取代对环境有害且昂贵的氟碳化合物（fc）。无论涂层方法和固化温度如何，所得到的纹理表面的水接触角θ接近155度，均方根粗糙度（Rq）接近85 nm，与等效的FC功能化表面（θ = 157度，R-q = 100 nm）相当。功能化的纳米颗粒可以被涂覆在各种衬底上以生成不同的超疏水材料。
We present a new class of superhydrophobic surfaces created from low-cost and easily synthesized aluminum oxide nanoparticles functionalized carboxylic acids having highly branched hydrocarbon (HC) chains. These branched chains are new low surface energy materials (LSEMs) which can replace environmentally hazardous and expensive fluorocarbons (FCs). Regardless of coating method and curing temperature, the resulting textured surfaces develop water contact angles theta of similar to 155 degrees and root-mean-square roughnesses (Rq) approximate to 85 nm, being comparable with equivalent FC functionalized surfaces (theta = 157 degrees and R-q = 100 nm). The functionalized nanoparticles may be coated onto a variety of substrates to generate different superhydrophobic materials.
