When using a wrench, the nut is easily damaged due to improper operation or impact. Although coating a polymer layer on the surface of the wrench can effectively solve the above problem, the layer is easy to be deboned due to the lack of adhesion between the polymer and the surface of the wrench. Herein, we implemented an anodizing treatment strategy on the surface of the wrench to obtain a porous oxide film. Interestingly, during the anodization process, micro-nanopores with a specific diameter can be obtained by adjusting the voltage, temperature, and electrolyte concentration. Furthermore, the ammonium fluoride/ethylene glycol electrolyte was used to etch the formed large hole to form the large hole sleeve small hole structure. In order to inject polyphenylene sulfide (PPS) molecules into multiscale holes to form a pinning effect, we also used nano molding technology to inject PPS into the metal surface. The results showed that the adhesion between PPS and the wrench was greatly improved compared with the commonly used dip coating method.

纳米钉扎作用的聚苯硫醚涂层扳手复合材料

使用扳手时，由于操作不当或撞击，螺母很容易损坏。尽管在扳手的表面上涂覆聚合物层可以有效地解决上述问题，但是由于聚合物与扳手的表面之间缺乏粘附性，该层易于剥离。在这里，我们在扳手的表面上实施了阳极氧化处理策略，以获得多孔氧化膜。有趣的是，在阳极氧化过程中，可以通过调节电压，温度和电解质浓度来获得具有特定直径的微纳米孔。此外，使用氟化铵/乙二醇电解质蚀刻形成的大孔以形成大孔套筒小孔结构。为了将聚苯硫醚（PPS）分子注入多尺度孔中以形成钉扎效应，我们还使用了纳米成型技术将PPS注入金属表面。结果表明，与常用的浸涂法相比，PPS与扳手之间的附着力得到了极大的改善。
