Embodiment 1
[0023] A mesoporous zirconium phosphate-loaded nano-silver antibacterial polylactic acid fiber includes a polylactic acid matrix, and mesoporous zirconium phosphate-loaded nano-silver antibacterial powder is dispersed in the polylactic acid matrix.
[0024] The preparation method of the above-mentioned mesoporous zirconium phosphate loaded nano-silver antibacterial polylactic acid fiber, the specific steps are:
[0025] (1) Mesoporous zirconium phosphate is treated with oleum to obtain mesoporous zirconium phosphate with sulfonic acid groups on the surface. The specific steps for treating mesoporous zirconium phosphate with oleum are: oleum with a mass fraction of 98% and mesoporous zirconium phosphate The mass ratio of pore zirconium phosphate is 10:1, the reaction temperature is 40° C., and the reaction time is 20 minutes.
[0026] (2) Take silver nitrate, ethylene glycol, and mesoporous zirconium phosphate with sulfonic acid groups on the surface at a mass ratio of 0.5:39.5...
