Eco-friendly and Durable Antibacterial Cotton Fabrics Prepared with Polysulfopropylbetaine

Construction of antibacterial fabrics with polymer cationic broccolo‐shaped nanoparticles

“…Finally, the antibacterial activity and hydrophobicity of PCBsNPs@CF was compared with reported antibacterial CF (Table 1). For example, polysulfopropylbetaine (PSPB), 43 hinokitiol‐ grafted‐chitosan (HTCS) 44 and organic/inorganic composite P(DMDAAC‐AGE‐Si)/(ZnO@CQDs) 45 were used as antibacterial agents and applied to cotton fabric. But they were hydrophilic and lacked bacterial anti‐adhesion studies.…”

Highly efficient and durable antibacterial cotton fabrics finished with zwitterionic polysulfobetaine by one-step eco-friendly strategy

“…SPB was synthesized in a similar fashion as the procedure of our previous work (Zhou 2018 ). Briefly, 1,3-propanesultone (5.99 g, 0.049 mol) was dissolved in 50 mL THF under stirring at 500 r/min.…”

“…This could be attributed to the broad-spectrum bacteriostatic and lethal effects of SPB, as derivatives of betaine with capacity to be amassed intracellularly at molar levels from extremely dilute Solutions (Cosquer 2004 ), which may inhibit the growth of microbes. Previous studies have established that this amphiphilic monomer can be used for polymerization (Zhou 2018 ). The proposed reaction mechanism of the grafting was that the epoxy groups of the polymer chains and the hydroxyl groups on cotton surface formed a covalent bond, thus obtaining functionalized cotton textiles as shown in scheme 1 .…”

“…These results show that essential cotton properties can be largely preserved in the treatment process. It is noted that we prepared AFA by polymerization (PSPB) of SPB and maleic anhydride and apply for the treatment of cotton textiles in our previous work, resulting in the breaking strength retention after finishing is 91.93% (Zhou 2018 ). However, the mechanical performance of cotton fabrics treated with PSPB-AM-AGE in this work was improved than PSPB finished cotton textiles, which may attribute to the reason, that AGE could link the antibacterial agents with cotton fabrics leading to less damage to cellulose fibers than that of maleic acid.…”

“…There had been no systematic study on the control of polysulfobetaine on cotton textiles to form a robust antimicrobial surface. Our previous work indicated that sulfopropylbetaine copolymers bearing carboxylic groups can provide a durable grafting layer on cellulose fibers with improved microbicide potency (Zhou 2018 ). Since the pH of AFA is low and the temperature of the finishing process is high, there is an obvious decline in the breaking strength of finished textiles, thus could not meet the required mechanical property.…”
