Bioinspired Superhydrophobic Progress and Recent Advances of Its Functional Application

“…刻蚀修饰法是最简单的实现人工超疏水表面 的方法, 该方法通过化学湿法刻蚀 [35][36][37][38][39] 、激光刻 蚀 [40][41][42][43][44] 、机械加工处理 [45][46] [47][48] 制备超疏水涂 层, 金属试样通过阳极氧化过程构建微米/纳米级粗 糙结构, 然后采用低表能物质对其进行超疏水修饰, 最终在金属表面制得超疏水膜, 该方法获得的超疏 水涂层通常较薄且机械耐久性较差。随着研究的不 断深入, 研究者采用电镀、电化学沉积的方式 [49][50][51][52][53][54] 制备多层叠加的超疏水涂层, 该涂层有利于实现超 疏水在腐蚀防护领域的工程应用。随着电化学沉 积法的进一步发展, 研究者采用电化学纳米共沉积 法 [55] 制备超疏水涂层, 采用电化学等离子处理结合 电化学沉积法 [56] 提升超疏水涂层的机械耐久性, 以 及采用水热法结合电化学沉积法 [57][58] [59][60][61] , 为了实现大规模化、工艺简单、低成 本、可操作性强的超疏水涂层, 基于溶胶-凝胶法的 浸涂或刷涂的方式 [62][63][64][65] 受到研究者广泛的关注, 为 了进一步提高涂层与基体的结合力, 喷涂固化的方 式 [66][67][68][69][70] 得到更为广泛的应用。…”

Preparation of Iron Ore Tailings-Based Superhydrophobic Coatings

“…Alternatively, aluminum, copper, and other bulk metal surfaces are employed as raw materials, followed by the corrosive dissolution, mechanical abrasion, and other processes to form a rough surface. Subsequently, spraying the nanoparticles modified with low surface energy modifier leads to the preparation of the superhydrophobic coatings [16][17][18][19]. However, the complicated and expensive preparation methods and the low stability of most of the reported superhydrophobic coatings limit their practical application.…”

Preparation of superhydrophobic nylon-56/cotton-interwoven fabric with dopamine-assisted use of thiol–ene click chemistry

“…There are two key points to consider when preparing superhydrophobic surfaces, namely, the construction of the micro–nano roughness and the use of materials with low surface energies. 9–11 Scientists have developed multiple preparation methods, including nanoparticle loading, 12 layer-by-layer assembly, 13 and chemical vapour deposition. 14 Using these methods, research institutions successfully created superhydrophobic surfaces on different substrates to meet various complex and changeable requirements.…”
