Hangzhou GeLanFeng Nanotechnology was established in 2011 to focus on graphene and related 2D materials.
GeLanFeng supplied monolayer and few-layer CVD graphene and MoS2 and also graphene flakes (GNP) powders, mostly to University research teams. The company also developed graphene applications and IP.
It seems that GeLanFeng is no longer in business. Its web site was gelanfeng.net.
