Abstract
A method for producing a carbon-coated member includes a step of heating a coating composition including a carboxylic acid anhydride and sulfuric acid in a state in which a portion or the entirety of a surface of a member to be coated is in contact with the coating composition, and a concentration of the sulfuric acid in the coating composition before heating is 0.4% by mass or more based on the sum of masses of the carboxylic acid anhydride and the sulfuric acid.
Claims9
A method for producing a carbon-coated member, the method comprising:
- a step of heating a coating composition including a carboxylic acid anhydride and sulfuric acid in a state in which a portion or the entirety of a surface of a member to be coated is in contact with the coating composition,
- wherein a concentration of the sulfuric acid in the coating composition before heating is 0.4% by mass or more based on a sum of masses of the carboxylic acid anhydride and the sulfuric acid.
A coating composition used for carbon-coating a surface of a member to be coated,
- the coating composition comprising a carboxylic acid anhydride and sulfuric acid,
- wherein a concentration of the sulfuric acid is 0.5% by mass or more based on a sum of masses of the carboxylic acid anhydride and the sulfuric acid.
A method for producing a carbonaceous material, the method comprising:
- a step of heating a carboxylic acid anhydride in the presence of a sulfuric acid within a system,
- wherein an amount of the sulfuric acid present in the system before heating is 0.4% by mass or more based on a sum of masses of the carboxylic acid anhydride and the sulfuric acid.
