Novel water-soluble amphiphilic ternary graft copolymers(COS-g-PCL-b-MPEG) were synthesized by N,N′-dicyclohexyl carbodiimide(DCC) coupling reaction between chitooligosaccharide(COS) with MPEG-b-PCL-COOH,which was sy...
A building unit(defined as SBU) synthesized from 1,2,4,5-benzene tetracarboxylic acid and 4-hydroxy pyridine was used as the gelator with low molecular weight to form supramolecular hydrogels at various concentrations...
