采用一种新颖、简便的自然制备方法，制备了一种超疏水、超亲油聚合物渗透纳米粒子薄膜包覆不锈钢网(PINF-SSM)。该方法包括使用低成本的原材料和在不锈钢网(SSM)表面简单地喷涂疏水性二氧化硅纳米颗粒。两面都有丙烯酸树脂预涂覆层，在树脂的玻璃化转变温度以上进行热处理后，可以方便地在SSM上转化为一体化的聚合物渗透纳米颗粒膜。得到的PINF-SSM在与砂纸多次摩擦、长期紫外线照射、长期储存以及暴露在强酸、碱和盐水溶液中后，表现出强大的超疏水性。所制备的PINF-SSM被成功地用于各种油水混合物的高效分离，至少循环50次，并有效地收集水面浮油。SSM表面顺序涂覆热塑性丙烯酸树脂和疏水二氧化硅纳米颗粒，使涂层材料的储存时间延长，高二氧化硅含量的树脂加工容易，修复速度快，超疏水表面易于恢复，使其适用于各种油水分离实践。
A superhydrophobic and superoleophilic polymer-infiltrated nanoparticle film-coated stainless-steel mesh (PINF-SSM) was prepared with a novel and facile nature-inspired approach. The approach involves the use of low-cost raw materials and simple spray coating of hydrophobic silica nanoparticles onto stainless-steel mesh (SSM) surface. With acrylic resin pre-coating layer on both surfaces, it is conveniently transformed into an integrated polymer-infiltrated nanoparticle film on SSM after annealing above the resin’s glass transition temperature. The obtained PINF-SSM shows robust superhydrophobicity after multiple cycles rubbing with sandpaper, long-term UV irradiation, long-term storage, and exposure to strong acidic, alkaline, and saline solutions. The as-prepared PINF-SSM was successfully used to separate various oil/water mixtures with high-efficiency for at least 50 cycles and collect oil slick on water surface efficiently. Sequential coating thermoplastic acrylic resin and hydrophobic silica nanoparticles on the surface of SSM allow for extended storage time of the coating materials, easy resin processing with high silica content, quick repairing, and easy recovery of the superhydrophobic surface, making it suitable in various oil/water separation practices.
