Abstract
Disclosed is a method for preparing a bilayer scaffold through single process comprising: preparing a first polymer aqueous solution; adding a second polymer into the first polymer aqueous solution and stirring a reactant; adding a surfactant into the stirred reactant and stirring the reactant at high temperature and high speed; freeze-drying the stirred reactant thereby obtaining a sponge; dipping the sponge in a cross-linking agent thereby rendering be cross-linked; and freeze-drying the cross-linked reactant.
