To improve the hydrophobic character of silk and impart iodine complex ion adsorption, the surface of woven silk fabric is enriched by different functional groups through the grafting of N‐vinylpyrrolidone (NVP), ethylene glycol dimethacrylate (EGDMA), and their mixtures (NVP–EGDMA). The dominant fibrous texture of silk enables an efficient graft copolymerization in terms of high grafting yield (>30%) after applying a mild degumming process. The structural and morphological alterations in the silk surface are evidenced with attenuated total reflectance‐fourier transform infrared spectroscopy (ATR‐FTIR), X‐ray diffraction (XRD), and scanning electron microscopy (SEM) techniques. The imparted hydrophilicity property of the samples is revealed by contact angle–wetting time measurements. The usability of the graft‐modified samples as an iodophor polymeric substrate is then examined by treatment with I2/KI solutions, and the results are monitored using UV–vis spectroscopy. It is obtained that the NVP–EGDMA mixture‐grafted sample exhibits satisfactorily high iodine adsorption compared to untreated and NVP‐grafted silk samples, such as 0.05 g per 1 g fabric with high antibacterial activity against various pathogens, including methicillin‐resistant Staphylococcus aureus (MRSA) responsible for hospital‐acquired infections. This finding evidences its potential as an alternative antiseptic tissue for biomedical applications.

通过接枝改性和碘伏集成增强抗菌性能的丝织物表面设计

为了改善蚕丝的疏水特性并赋予碘络合离子吸附作用，通过接枝不同的官能团，在机织丝织物的表面富集不同的官能团。氮‐乙烯基吡咯烷酮（NVP）、乙二醇二甲基丙烯酸酯（EGDMA）及其混合物（NVP-EGDMA）。蚕丝的主要纤维结构使得在采用温和脱胶工艺后能够实现高效的接枝共聚，接枝率高（>30%）。衰减全反射傅里叶变换红外光谱 (ATR-FTIR)、X 射线衍射 (XRD) 和扫描电子显微镜 (SEM) 技术证明了丝绸表面的结构和形态变化。通过接触角-润湿时间测量揭示了样品所赋予的亲水性。然后通过 I 处理来检查接枝改性样品作为碘伏聚合物底物的可用性。2/KI 溶液，并使用紫外可见光谱监测结果。结果表明，与未处理和 NVP 接枝丝绸样品相比，NVP-EGDMA 混合物接枝样品表现出令人满意的高碘吸附量，例如每 1 g 织物吸收 0.05 g 碘，对各种病原体（包括耐甲氧西林）具有高抗菌活性金黄色葡萄球菌(MRSA) 是医院获得性感染的罪魁祸首。这一发现证明了其作为生物医学应用替代防腐组织的潜力。
