Abstract

The organosilicon quaternary ammonium salt/(zinc oxide@carbon quantum dots) composite material referred to P(DMDAAC-AGE-Si)/(ZnO@CQDs) was prepared with ZnO, glucose and vinyl monomers by situ free-radical polymerization, which was applied into cotton fabrics at different concentrations. It was proved that the antibacterial cotton fabrics had been successfully prepared by FT-IR, SEM, TEM, antibacterial tests (shake flask tests) etc. The antibacterial rate was 98.38% and 99.53% against S. aureus and E. coli, respectively, when the concentration of the treating solution of composites reached to 25 g/L. Even after washing 10 times (equivalent to 50 household washing), the antibacterial rate remained above 89.65% against S. aureus and E. coli. In addition, the hydrophilic properties and air permeability of the treated cotton fabrics were enhanced.
