A few days ago, I got news from the National Standards Committee that two graphene national standards led by Taizhou Juna New Energy Co., Ltd. have passed the national standard project for comments. Has a strong competitive advantage and strength.
One standard is "Terminology and Definition of Graphene Materials", which intends to stipulate the terms and definitions of graphene materials, so that they are suitable for the production, application, inspection, circulation, scientific research and other fields of graphene materials, as a unified technology. The basis for the terminology; another standard is "Determination of the Number of Graphene Layers by Optical Method", which intends to stipulate the test methods, instruments, analysis steps, results representation methods, etc. of the optical (contrast) method to determine the number of graphene layers prepared by various methods.
