具有高疏水性的抗菌材料具有蛋白质吸附等缺点,细菌污染,和生物膜的形成,这是一些严重的不良健康事件的原因。因此,具有高亲水性的抗菌材料是非常需要的。在本文中,可UV固化的抗菌材料由含有机硅的氯化胆碱(ChCl)官能化的超支化季铵盐(QAS)和丙烯酸三羟乙酯磷酸酯(TAEP)制备。该材料显示出高亲水性能,因为它们的水接触角低至19.3°。该材料对金黄色葡萄球菌的抗菌效率也超过95.6%,相当高的透光率超过90%,力学性能良好,抗拉强度高达6.5MPa。这表明,从有机硅改性的ChCl功能化的超支化QAS中开发具有低疏水性的抗菌材料是一种可行的策略。
Antibacterial materials with high hydrophobicity have drawbacks such as protein adsorption, bacterial contamination, and biofilm formation, which are responsible for some serious adverse health events. Therefore, antibacterial materials with high hydrophilicity are highly desired. In this paper, UV-curable antibacterial materials are prepared from silicone-containing Choline chloride (ChCl) functionalized hyperbranched quaternary ammonium salts (QAS) and tri-hydroxylethyl acrylate phosphate (TAEP). The materials show high hydrophilic performance because their water contact angle is as low as 19.3°. The materials also exhibit quite high antibacterial efficiency against S. aureus over 95.6%, fairly high transmittance over 90%, and good mechanical performance with tensile strength as high as 6.5 MPa. It reveals that it is a feasible strategy to develop antibacterial materials with low hydrophobicity from silicone-modified ChCl-functionalized hyperbranched QAS.
