随着材料技术的不断发展,纳米银逐渐进入研究者的视野,由于其具有高表面能、量子尺寸效应及体积效应,因而在光学材料、电化学材料、生物传感器材料和抗菌材料等领域得到了广泛的应用.采用一步水热法,以葡萄糖为碳源、硝酸银为银源,在水热温度190℃的条件下制备出三明治结构的银碳复合材料,该材料同时实现了碳微球对银纳米粒子的包覆与负载.利用场发射扫描电子显微镜、透射电子显微镜、傅立叶红外光谱仪、X-射线衍射仪及热重分析仪等检测手段表征了产物的形貌和结构特征.结果表明:在水热条件下碳微球同时实现了对银纳米粒子的包覆与负载;所得三明治结构复合物表面含有大量含氧官能团且表面显负电性;热重分析表明复合物的含银量约为5.51%.抗菌实验分析表明样品对大肠杆菌和金黄色葡萄球菌具有良好的抗菌性,可以作为抗菌材料.
