Abstract:
1. An antibacterial sol-gel coating solution, prepared by a method consisting of: combining materials consisting of: 0.1 to 45% by weight of the total solution of at least one substance selected from the group consisting of Ti- or Si-containing compounds capable of hydrolyzing to form a base film, wherein the Ti- or Si-containing compounds are selected from the group consisting of butyl titanate, isobutyl titanate, ethyl titanate, n-propyl titanate, isopropyl titanate, titanium tetrachloride, titanium trichloride, titanium dioxide nanoparticle, tetraethyl orthosilicate, tetramethyl orthosilicate, tetrapropyl orthosilicate, tetrabutyl silicate, tetraisopropyl orthosilicate, and tetraisobutyl silicate; a regulating agent capable of regulating the hydrolysis rate of the Ti- or Si-containing compounds selected from the group consisting of acetylacetone and dimethyl formamide; an organic solvent; 0.001-15% by weight of the total solution of water; and 10-25% by weight of at least one soluble compound of an antibacterial metal on the basis of the total weight of the solution, said antibacterial metal being selected from the group consisting of Ag, Cu, Mg, Sn, Fe, Co, and Ni; wherein the at least one substance selected from the group consisting of Ti- or Si-containing compounds, the regulating agent, and a portion of the organic solvent are first mixed to form a solution I, then the water and the rest of the organic solvent are mixed and added into solution I to form a dispersion II, and finally the at least one soluble compound of an antibacterial metal is added into dispersion II to form the antibacterial sol-gel coating solution.
