Description
Technical Field
The invention belongs to the technical field of hydrophilic anti-fog coating preparation, and particularly relates to a homogeneous phase composite transparent hydrophilic anti-fog coating taking silicon-doped carbonized polymer points as construction elements and a preparation method thereof.
Background
Fog on the surface of a material is a common natural phenomenon, and the fog often brings a plurality of inconveniences to daily life and work of people. A simple method for solving the problem of fog is to coat a layer of hydrophilic coating on the surface of a material, wherein the hydrophilic coating has high surface energy, and when fog contacts the surface of the hydrophilic coating, liquid drops condensed on the surface can be quickly spread into a layer of water film, so that the formation of small liquid drops is prevented, and an anti-fog effect is achieved. However, hydrophilic coatings have low mechanical strength, thus limiting their useful life. In order to increase the surface hardness of the hydrophilic coating, it is often used to incorporate inorganic nanoparticles (e.g., silica). However, nanoparticles are easily aggregated in the coating medium, causing phase separation of the material, affecting the optical transparency of the coating. How to realize homogeneous hybridization of an organic phase and an inorganic phase in the coating is the key for solving the phase separation of the composite hybridization material.
The carbonized polymer dots are used as nano particles with a core-shell structure and the size of the nano particles is smaller than 10nm, and the carbonized polymer dots are used as finite field elements, so that the hybridization of an organic phase and an inorganic phase in the nano size range can be realized, and the occurrence of phase separation is avoided. Chinese patent CN113105766B uses aminosilicone and citric acid as precursors, prepares silicon doped carbonized polymer dot nano particles through hydrothermal reaction, can be used as a coating, and prepares a superhard, wear-resistant and scratch-resistant transparent optical coating. However, the anti-fog agent does not have anti-fog performance, and hydrophilic groups (hydroxyl groups) are introduced on the surface of the anti-fog agent to endow the anti-fog agent with anti-fog performance.
