为了提高银功能化抗菌棉织物的耐洗性,本文报道了辐射诱导的同时还原和接枝聚合,其中由于氨基和银之间的配位力,可以形成高达500nm的石榴形银纳米粒子聚集体,并且包裹过程源自银纳米粒子和聚合物接枝链的同时生长。这种石榴形银NPAs功能化棉织物具有出色的抗菌活性和优异的耐洗性,对两种E的灭活率高达90%以上。科利安德S.即使经过 50 次加速洗涤周期(相当于 250 次商业或家庭洗涤周期)后,仍可保持良好状态。
To improve the laundering durability of the silver functionalized antibacterial cotton fabrics, a radiation-induced coincident reduction and graft polymerization is reported herein where a pomegranate-shaped silver nanoparticle aggregations up to 500 nm can be formed due to the coordination forces between amino group and silver and the wrapping procedure originated from the coincident growth of the silver nanoparticles and polymer graft chains. This pomegranate-shaped silver NPAs functionalized cotton fabric exhibits outstanding antibacterial activities and also excellent laundering durability, where it can inactivate higher than 90% of bothE. coliandS. aureuseven after 50 accelerated laundering cycles, which is equivalent to 250 commercial or domestic laundering cycles.
