▎ 摘  要

NOVELTY - A polyvinyl-alcohol-type composite fiber comprises polyvinyl alcohol type polymer (A) and oxidation graphene particles (B), and has Young's modulus of 10 GPa or more. The ratio of polyvinyl-alcohol-type polymer (A) and oxidation graphene particles (B) satisfies preset relation. USE - Polyvinyl-alcohol-type composite fiber is used for industrial materials and cement reinforcement. ADVANTAGE - The polyvinyl-alcohol-type composite fiber has favorable Young's modulus without using carbon nanotube inducing aggregation. DETAILED DESCRIPTION - A polyvinyl-alcohol-type composite fiber comprises polyvinyl-alcohol-type polymer (A) and oxidation graphene particles (B), and has Young's modulus of 10 GPa or more. The ratio of polyvinyl-alcohol-type polymer (A) and oxidation graphene particles (B) satisfies relation: 0.01 less than or equal to 100x (B)/(A) less than or equal to 3. An INDEPENDENT CLAIM is included for manufacture of polyvinyl-alcohol-type composite fiber.
