    Preparation and Properties of Antimicrobial Hydrogel Dressing

      摘要
    • 摘要: 以乙二醇二缩水甘油醚(GDE)为偶联剂，将胍盐低聚物(PHMG)接枝到淀粉上，形成淀粉接枝物(Starch-g-PHMG)。然后，将一定比例的Starch-g-PHMG与淀粉 丙烯酸接枝共聚物共混，制备了抗菌水凝胶敷料(AHD)。通过红外光谱(FT-IR)、元素分析确定了Starch-g-PHMG的分子结构；通过吸液测试、抗菌测试表征了AHD的理化性能。结果表明:在反应温度为60 °C，反应时间为3 h，w(NaOH) = 0.4%时，Starch-g-PHMG 中PHMG的接枝效率最高，可达37.5%；AHD的吸液率随着Starch-g-PHMG含量的增加而减少；当w(PHMG) > 0.33%时，AHD对金黄色葡萄球菌与大肠杆菌的抑菌率可以达到100%。

       

      Abstract: Starch grafted oligoguanidine (Starch-g-PHMG) was synthesized using glycol diglycidyl ether as the coupling agent. Antimicrobial hydrogel dressing (AHD) was further prepared by blending Starch-g-PHMG with acrylic acid grafted starch. The molecular structures, physical and chemical properties of the prepared AHD were characterized via Infrared Spectroscopy (FT-IR), element analysis, fluid absorbency tests, and antimicrobial tests. Results showed that the maximum grafting efficiency (37.5%) could be achieved at the optimal reaction conditions as following: 3 h of reaction time at 60 °C and w(NaOH) = 0.4%. The fluid absorbency of AHD decreased with the increasing of Starch-g-PHMG content. The growth inhibition against E. coli and S. aureus reached 100% when w (PHMG) > 0.33%.
