摘　　要：为获取高效耐久的抗菌织物,以儿茶酚、乌托品和氯化锌等为前驱物,通过简便快捷的一步水热反应,在棉、锦纶及锦纶/棉等织物表面原位构筑纳米氧化锌/儿茶酚甲醛树脂结构,制得仿贻贝型耐久抗菌织物。借助扫描电子显微镜、X射线光电子能谱仪等对织物的形貌与化学构成进行测试与表征,分析了织物的抗菌、力学、手感、细胞毒性等性能及甲醛残留量。结果表明:纳米氧化锌被儿茶酚甲醛树脂固着在织物上,所得织物对革兰氏阳性菌、革兰氏阴性菌和真菌均具有高效的非溶出型抗菌作用,且耐水洗效果突出,在循环洗涤50次后的抑菌率仍高达99.99%;抗菌织物的断裂强力未明显下降,手感评分与原织物相近,细胞毒性较低,未检出甲醛残留。Objective Fabrics offer a growth environment for pathogenic microorganisms, which bring health risks to humans and affect the use of fabrics. It is an important demand to develop antibacterial fabrics that are harmful to different pathogenic microorganisms but benign to humans. Metal-based nanoparticles including ZnO nanoparticles are one of the most widely used antibacterial agents in the field due to their efficient and broad-spectrum antimicrobial activities in attacking bacteria and fungi. However, they often do not strongly bond with the fabric, causing the material to show poor laundering durability and suffer low stability in performance. Method Aiming for achieving efficient and durable antibacterial fabrics via a facile and applicable approach, a kind of one-pot hydrothermal reaction containing catechol, hexamethylenetetramine, and ZnCl2was performed, by which a kind of coatings composed of ZnO nanoparticles/catechol-formaldehyde resins(ZnO/CFR) were in-situ constructed on surfaces of both cellulosic and polyamide fabrics, and thus a series of mussel-inspired durable antimicrobial cotton, polyamide, and polyamide/cotton fabrics were obtained. In the system, catechol moieties of the resin are the origin of the superior adhesion capacity of the coating, contributing to the strong interfacial bonding with the material via covalent bonds and noncovalent interactions. Micro morphologies and chemical compositions of the fabric were studied by using scanning electron microscopy, X-ray photoelectron spectroscopy, and inductively coupled plasma optical emission spectrometry, and the antimicrobial activities, laundering durability, tensile strength, hand feel, mammalian cell viability and formaldehyde content of the fabric were tested and analyzed, respectively.Results It was found that all the coated fabrics turned yellow and some particles appeared randomly on surfaces of the fabrics(Fig. 1). ZnO/CFR coated samples presented Zn2p spectra with a double band corresponding to Zn2p1/2and Zn3p3/2, having two peaks at
