Publication number: 20150166346Abstract: In a method of fabricating graphite films, mesophase pitch, a polymer material and an organic solvent are used to produce a carbon precursor slurry, and the carbon precursor slurry is coated to produce the graphite films. Since the method of using natural graphite as a raw material in production requires a number of purification processes to manufacture an expanded graphite powder before the graphite films can be produced, and thus the fabricating cost is very high, and other high-priced materials such as polyimide (PI) or graphene also will increase the total cost.Type: ApplicationFiled: December 18, 2013Publication date: June 18, 2015Applicant: Chung-Shan Institute of Science and Technology, Armaments Bureau, M.N.DInventors: Hsin-Ping Chang, Cheng-Jung Ko, Chin-Wei Kuo, Chuen-Ming Gee, Pai-Lu Wang, Ching-Jang Lin, Dam-Ming Chiou

Patent number: 8916126Abstract: In a method of fabricating graphite flakes applied in a graphite nanomaterial, mesophase pitch and an organic solvent are used to produce a carbon precursor slurry, and the carbon precursor slurry is coated by a scraper to produce the graphite flakes. Since the method of using natural graphite as a raw material in production requires a number of purification processes to manufacture an expanded graphite powder before the graphite flakes can be produced, and thus the fabricating cost is very high, and other high-priced materials such as polyimide (PI) or graphene also will increase the total cost.Type: GrantFiled: December 18, 2013Date of Patent: December 23, 2014Assignee: Chung-Shan Institute of Science and Technology, Armaments Bureau, M.N.D.Inventors: Chung-An Wang, Chun-Han Lin, Chuen-Ming Gee, Pai-Lu Wang, Ching-Jang Lin, Chia-Wei Liao
