Abstract

Developing antibacterial materials is an efficient way to reduce the risk of harmful microorganism to human body. As a kind of popular textiles, cotton fabric (CF) is easy to breed microorganism and it is necessary to render it with biocidal effect. In this work, a water-soluble N-halamine precursor, (E)-1-(4-(allyloxy)phenyl)-N-(2-(piperazin-1-yl)ethyl)methanimine (APPEM), was synthesized and grafted onto cotton fabric through an argon plasma-induced grafting polymerization process. Afterward, the grafted cotton fabric was exposed to dilute sodium hypochlorite solution to change N–H bond into N–Cl bond and then the antibacterial cotton fabric (CF-APPEM-Cl) was obtained. The treated cotton fabric presented considerable biocidal efficacy and stability against UV light, washing, and storage. Escherichia coli (6.63 logs) and Staphylococcus aureus (6.44 logs) could be effectively inactivated within 60 min. Also, the oxidative chlorine on the fabric recovered over 76.9 and 81.5% after UV irradiation for 24 h and 50 washing cycles, respectively. And the oxidative chlorine remained 85% after 30 days of storage. Meanwhile, the mechanical properties of cotton fabric were hardly affected by this antibacterial treatment. This work provides a simple and efficient way to prepare antibacterial cotton fabric with high performance, which might be helpful to promote the development of antibacterial textiles.

氩等离子体诱导接枝聚合对棉织物进行抗菌改性

开发抗菌材料是降低有害微生物对人体危害的有效途径。棉织物作为一种流行的纺织品，易滋生微生物，有必要对其进行杀菌处理。本研究合成了水溶性N-halamine前体(E)-1-(4-(烯丙氧基)苯基)- n-(2-(哌嗪-1-基)乙基)甲胺(APPEM)，并通过氩等离子体诱导接枝聚合工艺将其接枝到棉织物上。然后，将接枝棉织物置于稀次氯酸钠溶液中，使N-H键转变为N-Cl键，得到抗菌棉织物(CF-APPEM-Cl)。处理后的棉织物在紫外线、洗涤和储存方面表现出良好的杀菌效果和稳定性。在60 min内可有效灭活大肠杆菌(6.63 log)和金黄色葡萄球菌(6.44 log)。紫外线照射24 h和50次洗涤后，织物上的氧化氯回收率分别达到76.9和81.5%。贮藏30天后，氧化氯含量保持在85%。同时，抗菌处理对棉织物的力学性能几乎没有影响。本研究为制备高性能抗菌棉织物提供了一种简单、高效的方法，对抗菌纺织品的发展有一定的推动作用。

期刊介绍： Publishing original papers on fundamental and applied research in plasma chemistry and plasma processing, the scope of this journal includes processing plasmas ranging from non-thermal plasmas to thermal plasmas, and fundamental plasma studies as well as studies of specific plasma applications. Such applications include but are not limited to plasma catalysis, environmental processing including treatment of liquids and gases, biological applications of plasmas including plasma medicine and agriculture, surface modification and deposition, powder and nanostructure synthesis, energy applications including plasma combustion and reforming, resource recovery, coupling of plasmas and electrochemistry, and plasma etching. Studies of chemical kinetics in plasmas, and the interactions of plasmas with surfaces are also solicited. It is essential that submissions include substantial consideration of the role of the plasma, for example, the relevant plasma chemistry, plasma physics or plasma–surface interactions; manuscripts that consider solely the properties of materials or substances processed using a plasma are not within the journal’s scope.
