石墨烯支持膜（Graphene Support Films for TEM）
石墨烯，一种只有一个原子厚的二维碳膜，这种新型材料化学性能稳定，很难与其他物质结合，石墨烯是目前发现的硬度***大的物质，有***的导电和导热性能，这些性能使得石墨烯极适于制作电镜载网支持膜。这种新型的石墨烯支持膜是在TEM的铜网或者有孔碳膜上做一层超薄的石墨烯薄膜，厚度在3个纳米以下，并且透明，这为TEM观测纳米粒子提供了极大的方便，对进行纳米粒子界面研究者非常有帮助，尤其是纳米颗粒较小且附着力较差时可以使用这种***的电镜载网。

二、PELCO® 石墨烯支持膜一般用300目载网的有孔碳膜上制作。可以提供出四种不同厚度的石墨烯支持膜：
- 单层石墨烯，厚度大约0.35nm
- 2层石墨烯，厚度大爷u.7nm
- 3-5层石墨烯，1.0-1.7nm
- 6-8层石墨烯，2.1-2.8nm
在石墨烯支持膜上大约75%的区域没有折叠和褶皱，这是可以用来放置样品的部位。石墨烯支持膜超薄（远远薄于碳膜）、导电，本身呈晶体结构，信号的噪音相对很低。
