Embodiment 1
[0075] Preparation of Coupling Agent Pretreated Inorganic Nanoparticles
[0076] The inorganic nanoparticles are pre-soaked with a coupling agent with a mass concentration of 0.1-5.0% for 5-60 minutes, and then dried at a temperature of 20-90°C for 5-60 minutes to prepare the inorganic nanoparticles treated with the coupling agent. Concrete preparation raw material and parameter are as follows:

Embodiment 2
[0079] Preparation of isotropic superhydrophobic and superoleophobic silicone rubber materials through anisotropic structure
[0080] (1) be that 40.0% vinyl silicone oil, 14.0% mass fraction are prepared by the embodiment 1 of 101 mass fraction, 0.5% Dow Corning RD27 platinum catalyst and 0.5% 1- The ethynyl-1-cyclohexanol inhibitor was uniformly mixed to obtain the first mixture. In the mixing process, the parameters of ball mill mixing are revolution 50r / min, rotation 100r / min, and time 40min.
[0081] (2) To the first mixture prepared in step 1, add a mass fraction of 40.0% hydrogen-containing silicone oil with a mass fraction of 2.0% Si-H groups and a mass fraction of 5.0% polyvinylidene fluoride silicone rubber Auxiliaries, continue to mix evenly, using ball milling parameters for revolution 50r / min, rotation 100r / min, time 60min, to obtain the second mixture. The second mixture was degassed in vacuum for 60 minutes to obtain "ink" for printing. Note: The mass fract...
