Problems solved by technology

[0003] The hydrophobic film formed by spraying hydrophobic and non-stick coatings on the surface of metal products generally has many problems in the industry, such as low hardness of the hydrophobic film, easy wear, easy peeling of the hydrophobic film, short service life, and the complex spraying film forming process requires repeated The spraying and sintering process can be completed many times, which is labor-intensive, time-consuming, and energy-intensive, and the electronic components made of these metal products generate a large amount of heat. If the heat cannot be exported in time, it will cause damage to itself

Abstract

The invention discloses a preparation method of a carbon polymer-based polyhedral oligomeric silsesquioxane hybrid hydrophobic membrane, and belongs to the technical field of membrane preparation. High strength and high thermal conductivity of the membrane layer are realized through an organic-inorganic hybridization process and formula, and a three-dimensional hollow cage-shaped network structure can be formed in a matrix by adopting an organic-inorganic hybrid polymer synergistically modified by modified graphene oxide, multi-walled carbon nanotubes and polysilsesquioxane. The modified graphene oxide and the multi-walled carbon nanotubes are combined, so that the mutual blocking effect of the modified graphene oxide and the multi-walled carbon nanotubes has an obvious inhibiting effect on mutual agglomeration, introduction of a hollow cage-shaped structure of the polysilsesquioxane can better support the spatial distribution capacity of the carbon nanomaterial in the matrix, so that the hardness is good, and the heat resistance is excellent; the graphene oxide is modified, and the graphene oxide is compounded with the nano boron nitride, so that the heat-conducting property is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of film preparation, and relates to a preparation method of a carbon polymer-based cage polysilsesquioxane hybrid hydrophobic film. Background technique [0002] In recent years, solid surfaces with hydrophobic properties have attracted intense attention. According to the hydrophilicity and hydrophobicity of the film, it can be divided into hydrophobic film and hydrophilic film. Among them, the film made of hydrophobic material is a hydrophobic film, and the contact angle formed by water droplets on the surface of the film is greater than 90°. At present, the hydrophobic mechanism of hydrophobic materials can be divided into two types: There are two types: one is to add micro-nano structures on the surface of the material, and the other is to reduce the surface energy of the material. [0003] The hydrophobic film formed by spraying hydrophobic and non-stick coatings on the surface of metal products general...
