| titleOfInvention | A kind of sulfonated citric acid chitosan modified polysulfone and preparation method thereof |
| abstract | A sulfonated citric acid chitosan modified polysulfone and a preparation method thereof, the main chain of the sulfonated citric acid chitosan modified polysulfone is a long polysulfone chain, and the side chain is covalently grafted with sulfonated citric acid Modified chitosan. The preparation method is as follows: firstly, a chloroacetyl group is grafted on the side chain of polysulfone (PSF) through a Friedel-Crafts-acylation reaction to obtain a chloroacetylated polysulfone (ClCH 2 CO-PSF); (EDA) was grafted on the side chain of chloroacetylated polysulfone to obtain aminated polysulfone (NH 2 -PSF); finally, the sulfonated citric acid modified chitosan (SCACS) was synthesized by the condensation reaction of carboxyl group and amino group. Grafted on the side chain of aminated polysulfone to obtain sulfonated citric acid chitosan-modified polysulfone (SCACS‑PSF). The invention is characterized in that the polysulfone side chain is covalently grafted with sulfonated citric acid to modify chitosan, which improves the hydrophilicity and anticoagulant property of the polysulfone; the process is simple and the reaction conditions are mild. |
