Water-resistant cellulose foam paper was developed in this work in an attempt to improve the antimicrobial activity of cellulose foam paper for capture and deactivation of pathogenic microorganisms existed in water. Results indicated that the cellulose foam paper could significantly improve household water quality by incorporating guanidine-based polymer modified with starch or called antibacterial...
Condensation polymerization was used in the preparation of modified guanidine polymers. The polymers were composed of hexamethylene diamine and guanidine hydrochloride with subsequent crosslinking of epichlorohydrin. The two-step synthesis method increased the molecular weight of guanidine polymers, and also enhanced the charge density of the polymer due to the formation of the four-membered rings...
Grafting guanidine polymer (PHGH) onto cellulose fibers was conducted via in situ free-radical polymerization using ceric ammonium nitrate (CAN) as an initiator. The optimum reaction conditions were obtained, under which the grafting percentage and the grafting efficiency reached over 20% and 50%, respectively. Atomic force microscopy (AFM) images revealed that the grafted polymer tended to form grains...
