Preparation method of epoxy nanometer hybrid material with low surface energy

The invention relates to a preparation method of epoxy nanometer hybrid materials with low surface energy. The method comprises the following steps of: firstly, adequately stirring and uniformly mixing epoxy resin, a precursor with low surface energy, a catalyst, a solvent, and the like, placing into a reaction kettle, controlling reaction temperature and time to prepare an epoxy prepolymer containing nanometer particles with low surface energy in situ; then uniformly mixing with a proper amount of curing agent; curing under certain temperature and pressure, and then curing under higher temperature to finally obtain the transparent epoxy nanometer hybrid material with low surface energy. In the invention, the nanometer particles are prepared in situ in the epoxy prepolymer by a solvent thermal method, and the epoxy nanometer hybrid material with low surface energy is prepared by further curing, the reaction device is simple, the sizes and contents of the nanometer particles can be controlled according to actu
