| An N-halamine monomer, 3-methylallyloxy-5,5-dimethylhydantoin (MH) was synthesized by 5,5-dimethylhydantoin (DMH) and methacryloyl chloride. Antimicrobial coating of poly[1-methyl-1-(4,4-dimethyl-2,5-dioxoimidazolidin-carbonyl)ethylene] (PMH) were prepared on pristine cotton fabrics via a "mist polymerization" process using MH as monomer. The coating endowed the cotton fabric with effective antibacterial function and remarkable antibacterial durability. In the antibacterial tests, the bacteriostatic reduction rate against both Escherichia coli and Staphylococcus aureus is greater than 99.78%, and can be maintained over 99.00% even after 30 cycles washing. Compared with other antimicrobial technologies, mist polymerization offers advantages such as, achieving antimicrobial function by small consumption of monomer, forming coatings on single-side of the fabrics, and minimizing the damages on the original properties of cotton during the finishing process. It has potential applications in a wide variety of fields such as sportswear, socks, underwear, and medical textile. |
