Example Embodiment
[0045]Example 1
[0046]A method for preparing antibacterial, mildew-proof and degradable plastics. Firstly, epoxidize the dioxanone-ε-caprolactone copolymer to obtain an epoxidized product, and then separate the epoxidized product with modified nano-fillers. The modified polymer is obtained by the ring reaction, and then the modified polymer and the modified collagen are mixed and melted, extruded, cast, and then processed to obtain the antibacterial, mildew, and degradable plastic; wherein, the modified nanofiller It is prepared by the following method:
[0047](A) First use ammonium molybdate, selenium powder, and zinc powder as raw materials, and produce zinc-doped molybdenum selenide nanospheres through hydrothermal reaction;
[0048](B) Then the zinc-doped molybdenum selenide nanospheres are modified with N-β-(aminoethyl)-γ-aminopropylmethyldimethoxysilane to obtain modified nanospheres;
[0049](C) Finally, the polyhexamethyleneguanidine phosphate is dissolved in water, and then the modi...
