家园 不知道工艺

看起来是先加热石墨,气相沉积法CVD先沉积到铜表面,然后再用胶布大法,胶布从铜表面粘下来?

In Hong's method, a sheet of copper foil is wrapped around a cylinder and placed in a specially designed furnace. Carbon atoms carried on a heated stream of hydrogen and methane meet the copper sheet and settle on it in a single uniform layer. The copper foil exits the furnace pressed between hot rollers, and the graphene is transferred onto a polyester base.

另一种是用酸溶解,但出来的只能是一堆片片的混合,只能做复合材料,像碳纤维。
