Abstract

The invention belongs to the technical field of surface modification treatment of materials, and relates to a super-hydrophobic surface modification method based on a photothermal effect, and a surface super-hydrophobized material and application thereof. The method comprises the following steps: (1) carrying out surface pretreatment on a matrix material; (2) fluorinating an epoxy resin curing agent, and adding a photo-thermal material with a photo-thermal effect to prepare a super-hydrophobic coating material; and (3) initiating a thermal polymerization reaction of the epoxy resin through simple transfer and infrared thermal treatment to finish the super-hydrophobic modification of the surface of the matrix material. The super-hydrophobic coating material with the photo-thermal material is attached to the surface of the matrix material through simple coating, soaking and spraying methods, a preparation process is simple, equipment cost is low, and attachment is uniform; and meanwhile, a treatment condition is mild, the main body performance of various matrix materials cannot be damaged, and the surface performance of the matrix materials is effectively improved; and by introducing the photo-thermal material, the heat production capacity of illumination is improved, and wide application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of material surface modification treatment, and more specifically relates to a superhydrophobic surface modification method based on photothermal effect, a surface superhydrophobic material and its application. Background technique [0002] With the development of society, social infrastructure has been greatly enriched. However, various functional materials widely used in the fields of cargo transportation, communication facilities, and aviation and navigation have caused serious safety hazards and property losses to these fields because of their surface corrosion and icing. When superhydrophobic materials are used as coating materials for surface modification treatment, due to their unique micro-nano structure, they are one of the most effective metal anti-corrosion methods. To a certain extent, they are also conducive to delaying or alleviating surface icing. Phenomenon. However, in the natural environm...
