Abstract

ABSTRACT Recently, the need for effective antibacterial materials is growing day after day. Hydrogels with antimicrobial activities are strongly recommended in many biomedical applications. This work aims to prepare natural based nanocomposite hydrogel composed of N-vinyl pyrrolidone (NVP), acrylic acid (AAc) and pectin (PEC) embedded with silver nanoparticles (AgNPs). The prepared Poly(NVP/AAc/PEC/Ag) pH-sensitive nanocomposite hydrogel was characterized by gel (%), equilibrium swelling, FTIR, SEM, and XRD. Additionally, in order to confirm the incorporation of AgNPs within the nanocomposite hydrogel matrix during irradiation, TEM analysis was carried out. The AgNPs have average particles size 5.9 ± 1 nm for 10 kGy, 6.7 nm ± 2 for 20 kGy, and 8.9 ± 3 nm for 30 kGy, respectively. The XRD data are in good agreement with TEM analysis. The antibacterial activities of the selected Poly(NVP/AAc/PEC/Ag) nanocomposite hydrogel prepared at 30 kGy irradiation dose towards S. aureus, and E. coli has a higher antibacterial activity than other irradiation doses.

辐射合成聚(n -乙烯基吡咯烷酮/丙烯酸/果胶/银)纳米复合水凝胶及其抗菌活性

近年来，对有效抗菌材料的需求日益增长。具有抗菌活性的水凝胶在许多生物医学应用中被强烈推荐。本研究旨在制备n -乙烯基吡罗烷酮(NVP)、丙烯酸(AAc)和果胶(PEC)包埋银纳米粒子(AgNPs)的天然基纳米复合水凝胶。采用凝胶(%)、平衡溶胀、FTIR、SEM、XRD等手段对制备的Poly(NVP/AAc/PEC/Ag) ph敏感纳米复合水凝胶进行表征。此外，为了确认在辐照过程中AgNPs在纳米复合水凝胶基质中的掺入，进行了TEM分析。AgNPs的平均粒径在10 kGy时为5.9±1 nm, 20 kGy时为6.7 nm±2 nm, 30 kGy时为8.9±3 nm。XRD数据与TEM分析结果吻合较好。在30 kGy辐照剂量下制备的Poly(NVP/AAc/PEC/Ag)纳米复合水凝胶对金黄色葡萄球菌和大肠杆菌的抑菌活性高于其他辐照剂量。图形抽象

期刊介绍： Plastics, Rubber and Composites: Macromolecular Engineering provides an international forum for the publication of original, peer-reviewed research on the macromolecular engineering of polymeric and related materials and polymer matrix composites. Modern polymer processing is increasingly focused on macromolecular engineering: the manipulation of structure at the molecular scale to control properties and fitness for purpose of the final component. Intimately linked to this are the objectives of predicting properties in the context of an optimised design and of establishing robust processing routes and process control systems allowing the desired properties to be achieved reliably.
