Abstract (en)
[origin: WO2013096448A1] A composition of exceptionally dense chitosan and a novel method for producing the dense chitosan structure have been described. The novel production method employs coincident compression and vacuum on a neutralized chitosan polymer that results in an exceptionally dense chitosan film or membrane material. The dense chitosan film or membrane composition possesses multiple physical and clinically appealing qualities for a variety of medical applications on or in animals, mammals, or humans.
