Analog neural directional network structure bionic composite material applied to electrical stimulation, and preparation method thereof

The invention relates to an analog neural directional network structure bionic composite material applied to electrical stimulation, and a preparation method thereof. The method comprises the following steps: weighing a certain amount of polycaprolactone (PCL), adding a certain amount of a dichloromethane (DCM) and dimethyl formamide (DMF) mixed solution, and performing uniform stirring; adding acertain amount of modified magnetic nanoparticles to the above obtained solution, performing ultrasonic dispersion and uniform stirring, and performing an electrospinning technique to obtain a film material having a certain thickness; weighing an appropriate amount of carbon nanotubes, and acidifying the carbon nanotubes twice to obtain carbon nanotubes with carboxyl groups on the surface; and dispersing the surface-modified carbon nanotubes in a dispersant, coating the surface of the fiber film, and finally curling the obtained film to form a multilayer structure in order to obtain the targetproduct.
