Bionanocomposites hydrogel based on conducting polymers were successfully fabricated from chitosan/polyacrylic acid/polypyrrole (CS/PAA/PPy) as well as the magnetite nanoparticle (FeO-NPs) was prepared via co-precipitation method. In addition, different ratios of FeO-NPs were added to the prepared bionanocomposites to enhance the antimicrobial and the electrical conductivity of the prepared conductive hydrogel. Furthermore, the morphology, the swelling percent, antimicrobial activity and the dielectric properties of the prepared conducting bionanocomposites hydrogel were investigated. The antibacterial activities of the experienced microbes were improved with the increasing the loading of FeO-NPs in conducting Bio-nanocomposites hydrogel. Moreover, the DC-conductivity was examined and our resulted indicated that the DC-conductivity was enhanced by increasing the loadings of FeO-NPs compared to that of the pure CS/PAA as well as CS/PAA/PPy.
基于导电聚合物的生物纳米复合材料水凝胶是成功地由壳聚糖/聚丙烯酸/聚吡咯(CS/PAA/PPy)以及通过共沉淀法制备的磁性纳米粒子(FeO-NPs)制备的。此外,将不同比例的 FeO-NPs 添加到制备的生物纳米复合材料中,以提高制备的导电水凝胶的抗菌性和电导率。此外,还研究了制备的导电生物纳米复合材料水凝胶的形态、溶胀率、抗菌活性和介电性能。随着导电生物纳米复合材料水凝胶中 FeO-NPs 负载量的增加,经验微生物的抗菌活性得到提高。此外,还测试了 DC 电导率,结果表明,与纯 CS/PAA 以及 CS/PAA/PPy 相比,通过增加 FeO-NPs 的负载量可以提高 DC 电导率。
