摘要：

The PDMDAAC-AGE-MAA/nano-ZnO composite was prepared by dimethyl diallyl ammonium chloride (DMDAAC), allyl glycidyl ether (AGE), methylacrylic acid (MAA) and nano-ZnO via in-situ polymerization. The effect of the dosage of nano-ZnO on the performance of PDMDAAC-AGE-MAA/nano-ZnO composite was investigated, and the composite was characterized by FT-IR, XRD and TEM. Then cotton fabric was treated with PDMDAAC-AGE-MAA/nano-ZnO composite. The results show that when the dosage of nano-ZnO is 0.8%, the stability of PDMDAAC-AGE-MAA/nano-ZnO composite is the best; The characteristic absorption peaks of the epoxy groups and nano-ZnO exist in the PDMDAAC-AGE-MAA/nano-ZnO composite, Nano-ZnO is good dispersion in composite; Compared with the control cotton sample, the cotton treated with the PDMDAAC-AGE-MAA/nano-ZnO composite after 10 times of standard washing shows the precent reduction of antibacterial properties against Escherichia coli(E. coli) and Staphylococcus aureus(S. aureus) is above 80%, and the percent reduction of antibacterial properties against Candida albicans(C. albicans) is above 75%, because of the antibacterial properties of the synergistic effect by nano-ZnO and N+ in the composite. The PDMDAAC-AGE-MAA/nano-ZnO composite is coated on the surface of treated cotton fibers. After standard washing, the elements of Zn and N still remain in the treated cotton samples, the cotton treats with PDMDAAC-AGE-MAA/nano-ZnO composite possesses good washing fastness. Compared with the untreated cotton, the cotton treated with PDMDAAC-AGE-MAA/nano-ZnO composite has no effect on the breaking strength. ©, 2015, Beijing Institute of Aeronautical Materials (BIAM).
