GB/T 43104-2023 is an important standard in the field of carbon-based films. It formulates a systematic classification system for carbon-based films, scientifically divides them according to film characteristics and compositions, and clearly regulates naming rules. Through unified classification and naming, the problem of name confusion and disordered classification in the industry is solved, which is convenient for scientific research exchanges, product development and mass control. It helps to promote the standardization development of the carbon-based film industry and improve the overall level of the industry.
