Abstract: In the present work, ZnO particles loaded on activated carbon fiber (ACF) was prepared by dipping ACF in ZnO suspension, using glycol as dispersant. The antibacterial activity of the prepared sample ZnO/ACF was examined. The effect of surfactant (SDBS) on ZnO distribution, and the effect of loading ZnO on iodine adsorption capacity of ACF were studied. ACF loading 5.50% ZnO particles could significantly inhibit growth of S. aureus. Loading ZnO on ACF showed no significant influence on its iodine adsorption capacity. ZnO particles would be more uniformly distributed when surfactant was added in the suspension. The above results indicate that the prepared sample would be suitable for using as medical dressing.

摘要： 以活性碳纤维为载体,乙二醇为分散液,将碳纤维浸渍于含ZnO粉体的乙二醇溶液中制得ZnO/活性碳纤维样品,测试了样品的抑菌性,并比较了分散液中添加表面活性剂SDBS对ZnO分散的影响以及负载有ZnO前后碳纤维吸附性能变化。结果表明,表面吸附有5.50%ZnO的活性碳纤维对金黄色葡萄球菌抑制作用明显,且对碳纤维本身吸附性能影响不大,添加表面活性剂SDBS后能使ZnO的分布更加均匀,适合于用作医用敷料。
