[0062] A kind of preparation method of inorganic-multiple organic compound antibacterial agent, described preparation method specifically comprises the following steps:
[0063] 1) Modification of inorganic antibacterial agent: Dissolve 3-aminopropylmethyldioxysilane in ethanol aqueous solution (volume ratio 2:1), mix with zinc oxide with a particle size of 100nm in a high-speed disperser at a speed of 1200rpm After 10min, obtain modified zinc oxide (O-ZnO) through washing, drying; Wherein said 3-aminopropylmethyldioxysilane and zinc oxide account for the ratio of the percentage of both gross mass to be 1wt.%: 99wt.%;
[0064] 2) Dissolve O-ZnO powder in 150mL ethanol, add vanillin to it, stir for 3 hours, filter, wash, and dry at 60°C for 24 hours to obtain an inorganic-single natural structure organic composite antibacterial agent; wherein O-ZnO and The ratio of vanillin to the percentage of both gross mass is 91wt.%: 9wt.%;
[0065] 3) Dissolve thymol (THY) in dichloromet...
