제목 | Preparation and Properties of Chitosan-PEGmonosuccinate Polyelectrolyte Complex Films |
초록 | The term "polyelectrolyte" is employed for polymer systems consisting of a "macroion," i.e., macromolecule carrying covalently bound anionic or cationic groups, and low-molecular "counterions"securing for electroneutrality. Macromolecular complexes of different polymers are bound through intermolecular interactions, such as hydrogen bonding, Coulomb forces, Van Der Waals forces and transfer forces. According to the nature of interactions the complexes can be divided into: (1) Polyelectrolyte complexes, (2) charge-transfer, (3) hydrogen-bonding complexes, (4) stereocomplexes. Polyelctrolyte complex (PEC) was prepared by the formation of complexes from the interaction of oppositely charged polymers. We prepare The novel polyelectrolyte complex formed by interactions between chitosan and PEGmonosuccinate was established through two-step reactions. First, PEGmonosuccinate was synthesized by a 1:1 mole reaction of poly(ethylene glycol)(PEG) and succinic anhydride. And then, that was preparedby reaction of above synthesized PEGmonosuccinate and Chitosan. The present paper is focused on both the preparation of water-soluble, biocompatible, biodegradable and non-toxic polyelectrolyte complex and establishment of best condition in a novel polyelectrolyte complexes formed by interaction between two high-molecular weight compounds. |
