采用真空浸渍法和水热法制备了基于ZnO和氧化石墨烯(GO)的抗菌性能较好的竹材。Zn2+离子和GO纳米片首先渗入到竹结构中,随后在水热处理下脱水结晶,导致在大块竹中形成ZnO/GO纳米复合材料。采用扫描电子显微镜(SEM),傅里叶变换红外光谱(FTIR),X射线衍射(XRD)等技术对竹材进行了表征,证实了复合材料中存在GO和ZnO。通过抑菌圈法评价竹子样品的抗菌性能。 结果显示,ZnO/GO纳米复

Zn2+离子和GO纳米片首先渗入到竹结构中,随后在水热处理下脱水结晶,导致在大块竹中形成ZnO/GO纳米复合材料。采用扫描电子显微镜(SEM),傅里叶变换红外光谱(FTIR),X射线衍射(XRD)等技术对竹材进行了表征,证实了复合材料中存在GO和ZnO。通过抑菌圈法评价竹子样品的抗菌性能。

结果显示,ZnO/GO纳米复合材料在竹材中的引入产生了对大肠杆菌(革兰氏阴性)和枯草芽孢杆菌(革兰氏阳性)细菌具有明显抗菌活性并具有高热稳定性的ZnO/GO/竹材。预期抗菌竹子将成为家具,装饰和建筑行业应用的有前景的材料。
