Abstract
The antimicrobial and hemostatic activities of wound dressing drew more and more attention in the healthcare or medical industry. Here, the quaternary ammonium groups were introduced in the chitosan backbone via co-polymerization, and the quaternized chitosan was coated on the cotton fabric through the PDC process. Compared with BPTCD treated cotton (cotton/BPTCD), the breaking strength of CS-b-pSBMA coated cotton (cotton/SBMA) have not affected by the addition of CS-b-pSBMA. The SBMA coated cotton displayed good liquid adsorptive activity with or without pressure. As a dressing material, cotton/SBMA exhibited good hemostatic activity and hemocompatibility. After being challenged with E. coli O157:H7 and S. aureus for 60 min, cotton/SBMA showed good antimicrobial properties, and 100% bacteria was inhibited within the contact time. These attractive functions make the quaternized chitosan-coated cotton fabrics a good candidate for wound dressing materials.

期刊介绍：
The material innovations on surfaces, combined with understanding and manipulation of physics and chemistry of functional surfaces and coatings, have exploded in the past decade at an incredibly rapid pace.
Superhydrophobicity, superhydrophlicity, self-cleaning, self-healing, anti-fouling, anti-bacterial, etc., have become important fundamental topics of surface science research community driven by curiosity of physics, chemistry, and biology of interaction phenomenon at surfaces and their enormous potential in practical applications. Materials having controlled-functionality surfaces and coatings are important to the manufacturing of new products for environmental control, liquid manipulation, nanotechnological advances, biomedical engineering, pharmacy, biotechnology, and many others, and are part of the most promising technological innovations of the twenty-first century.
