| titleOfInvention | Tissue engineering double-layered tubular support and preparation method thereof |
| abstract | The invention relates to a tissue engineering double-layered tubular support and a preparation method thereof. The support is composed of two polymer layers with different pore structures, the inner layer is a compact nanofiber structure, and the outer layer is of a porous nanofiber structure. The preparation method comprises the following steps of: dissolving a polymer material in a solvent, pouring in a mould, performing phase separation overnight, demoulding to obtain a polymer gel, performing solvent replacement, and freeze drying to obtain a nanofiber tubular support with a compact structure; sleeving the nanofiber tubular support on a mould stem to obtain a casting mould; and dissolving a polymer material in a solvent, casing the polymer solution in the casing mould by combing an electroporation technology, performing phase separation overnight, demoulding, performing solvent replacement, removing the solvent and/or porogen, and freeze drying to obtain the tissue engineering double-layered tubular support. The preparation method disclosed by the invention is simple in operation, free of complicated equipment, suitable for large-scale production and low in preparation cost; the whole mechanical property of the support is improved by introducing other polymers in the phase separation system. |
