| titleOfInvention | Method for improving hydrophilic property and flexibility of polypeptide film by adopting polyurethane and polyacrylic acid |
| abstract | The invention discloses a method for improving the hydrophilic property and flexibility of a polypeptide film by adopting polyurethane and polyacrylic acid. The method comprises the following steps: 1) adding diisocyanate, polytetramethylene ether glycol, a catalyst and a solvent into a drying reactor, reacting for a period of time under an inert atmosphere, adding butanediol for reaction for a period of time, and then adding 3-hydroxypropionic acid for reaction, so as to obtain the polyurethane containing end carboxyl groups; 2) adding the polyurethane containing end carboxyl groups, a solvent, a condensing agent and a polypeptide homopolymer into the drying reactor, and reacting for 3-4 days under the inert atmosphere, so as to obtain a polypeptide-polyurethane segmented copolymer; 3) adding the polypeptide-polyurethane segmented copolymer, the polyacrylic acid and a solvent into the drying reactor, mixing for a period of time under the inert atmosphere, and performing film formation by adopting a tape-casting method, so as to obtain the target object. According to the invention, the preparation technology is simple, and the hydrophilic property and flexibility of the obtained modified film are greatly improved. |
