Abstract
A hydrophilic electrospinning biological composite scaffold material used for tissue regeneration and a preparation method and an application thereof are provided. Fibrinogen, L-arginine or an aqueous solution of hydrochloride thereof and a P(LLA-CL) solution are blended and an electrospinning technology is used to prepare the biological composite scaffold material. The biological composite scaffold material has an equilibrium contact angle that is less than 55°, is hydrophilic and has a good application prospect in repairing body tissue defects.
