Abstract
A method of producing a bioabsorbable membrane includes: forming a liquid membrane by spin-coating a coating liquid containing a first bioabsorbable polymer and a solvent; and forming a dense layer by causing a porous membrane containing a second bioabsorbable polymer to contact the liquid membrane.
Claims2
A method of producing a bioabsorbable membrane including a first layer containing a first bioabsorbable polymer and a porous layer containing a second bioabsorbable polymer, the method comprising:
- forming a liquid membrane by spin-coating a coating liquid containing the first bioabsorbable polymer and a solvent;
- and
- after forming the liquid membrane, forming the first layer and the porous layer by causing a porous membrane containing the second bioabsorbable polymer to contact the liquid membrane such that a part of the liquid membrane permeates into the porous membrane and by evaporating the solvent contained in the liquid membrane by drying.
