Embodiment 1
[0026] A method for preparing a superhydrophobic surface, comprising the steps in turn:
[0027] 1) Prepare the original solution: add perfluorooctyl ethyl acrylate into the container, seal it well and pour argon into the container at the same time;
[0028] 2) Stock solution pretreatment: inject the stock solution into the pipeline and preheat it at 120°C for 120 minutes to vaporize the stock solution;
[0029] 3) Plasma treatment: Under an argon atmosphere, conduct plasma treatment on the surface of polystyrene substrate, the conditions of plasma treatment are: vacuum degree 10mT, temperature 25°C, gas flow rate 50sscm, treatment power 60W, treatment time 100s;
[0030] 4) Grafting treatment: uniformly spray the stock solution treated in step 2) onto the surface of the polystyrene substrate treated in step 3) in a spraying manner, and simultaneously carry out plasma treatment on the surface of the polystyrene substrate, and the plasma The processing conditions are: vacuum ...
