Biomimetic material for shoulder joint and preparation method and application thereof

The invention discloses a biomimetic material for shoulder joint and a preparation method and an application thereof. The biomimetic material is composed of the following raw materials (by weight): 22-28 parts of montmorillonite, 45-58 parts of polyvinyl alcohol, 10-16 parts of poplar, 3-7 parts of graphite, 150-170 parts of ethanol, 110-125 parts of ammonia water and 8-15 parts of carragheenan. The preparation method comprises the following steps: crushing montmorillonite, polyvinyl alcohol, poplar and graphite for later use; treating montmorillonite powder with ethanol to prepare a montmorillonite pretreatment fluid; treating polyvinyl alcohol powder with ammonia water and adding the montmorillonite pretreatment fluid to prepare a mixture A; mixing poplar powder, graphite powder and residual ethanol and carrying out microwave treatment to prepare a mixture B; and stirring the mixture A, the mixture B and carragheenan, carrying out ultrasonic treatment and drying so as to obtain the biomimetic material.
