NOVELTY - A graphene-modified carbon felt preparing method involves preparing a placing rack, installing 10-20 grid plates on the rack, when the space between the upper and lower grid plates is 2-16 mm, placing the carbon felt on the grid plates, and placing the shelves in the acid solution for soaking, agitating the acid solution while soaking, so that the acid solution impacts the carbon felt, accelerating the soaking speed, and cleaning up the debris floating on the surface of the acid solution while stirring, after soaking, washing and drying the carbon felt, after heating is completed, taking out the carbon felt and cooling to room temperature to obtain the finished product. USE - Method for preparing graphene-modified carbon felt. ADVANTAGE - The method shortens the preparation time of the graphene-modified carbon felt and improves the preparation efficiency.
