NOVELTY - Method for preparing external-use orthosis composite material, involves using 55-65 pts. wt. polycaprolactone, 20-24 pts. wt. chitosan, 0.1-0.5 pt. wt. graphene, 14-15 pts. wt. acetic acid, 0.1-0.2 pt. wt. coupling agent and 0.1-3 pts. wt. stabilizer. USE - Method for preparing external-use orthosis composite material. ADVANTAGE - The method is simple, easy to master and economical, and ensures excellent low-temperature thermoplasticity and antibacterial properties, which changes the situation of long-term use of materials that are easy to breed bacteria, and makes the material stronger, thinner, strength and light.
