金属纳米粒子掺杂的柔性自支撑石墨烯薄膜的制备方法
摘要：
本发明公开了一种金属纳米粒子掺杂的柔性自支撑石墨烯薄膜的制备方法。首先将石墨烯和金属盐溶液混合，并将混合溶液滴定在固体基底上干燥成膜。将得到的薄膜放入抗坏血酸水溶液中加热还原，得到内部掺杂金属纳米粒子的柔性自支撑石墨烯薄膜。将氧化石墨烯水溶液首先滴定在固体基底上，并干燥成膜。再进一步将金属盐溶液滴定在氧化石墨烯膜上，干燥后放入抗坏血酸水溶液中加热还原，得到表面掺杂金属纳米粒子的柔性自支撑石墨烯薄膜。该方法制备简单，反应步骤少，操作方便，对设备、工艺要求简单，原料廉价，成本低，可实现内部掺杂金属纳米粒子的石墨烯薄膜及表面掺杂金属纳米粒子的石墨烯薄膜的制备。
