▎ 摘　　要

NOVELTY - Membrane material comprises polyurethane, silver nitrate, graphene oxide, and methylprednisolone. The membrane material is mixed with the components in a specific ratio as a solute, and added to a solvent composed of N,N-dimethylformamide and tetrahydrofuran to obtain a spinning solution, which is obtained by electrospinning. of nanofiber membranes. USE - Membrane material used in myocardial patch (claimed). ADVANTAGE - The membrane material has good conductivity, stable fluctuation of electric signals, high elasticity and high fracture strain. The performance can be kept stable under wet condition, and can effectively play a role as a myocardial patch. DESCRIPTION OF DRAWING(S) - The drawing shows a scanning electron microscope photograph of the prepared nanofiber membrane.
