英文摘要
(1) An approach to fabricate and precisely functionalize wormlike polymer brushes has been built. By this chemistry, novel dendronized polymers functionalized with PEGs tethered through metal complexation and crown ether units have been prepared. Codendronized polymers with wormlike morphologies have been prepared and they exhibited hierarchical ordered structure from molecular level to macroscopic scale. Moreover, dendronized polymers have been applied as building blocks to prepare various nanosized polymers. Also the amphilphilic polymer brushes have been obtained and their drug delivery properties have been evaluated. (2) A facile and generalized approach to produce polymeric nanoobjects with different shapes has been developed. By self-assembling, crosslinking and dispersing in solvent, various stable polymer particles of spherical, cylindrical and sheetlike shapes have been obtained. They are applying to study the shape resulted properties. (3) By using chemistry obtained above, novel well-defined polymers have been studied for materials application. The cyclodextrin induced polymer hydrogels have been applied to hybridize with functional species like carbon nanotubes and these novel materials demonstrate stimuli-responsive properties. The hydrogels hybridized with the nanoparticles bearing anticancer chemotherapy drugs exhibit new stepwise delivery properties. Under support, 14 PhD students have been graduated and 45 papers have been published so far. The principal becomes an Associate Editor of Polymers journal and Editorial advisory board of Macromolecules journal.
