Control of Periodicity of Mesoporous Cubic Networks of Hydrogels by Living Additive Manufacturing |
| 초록 |
Triply periodic minimal surfaces of block copolymer bilayers attract recent attention for their potential as nanotemplates of inorganics, metals, and polymers. Periodicity of the resulting network is dictated by that of the minimal surface template, and is difficult to control. Hydrogels having well-defined periodic structures are interesting materials for their enhanced physical responses under stimuli. Hydrogel nanonetworks exhibit dynamic periodicity when exposed to the different environments. We report replication of channels inside bicontinuous cubic mesophases of block copolymer bilayers. Two components having complementary reactivities were synthesized to form cross-links upon mixing. Trithiocarbonate groups embedded in the polymers serve as a point for chain extension by photo-catalyzed RAFT polymerization. The hydrogel networks were further modified to have increased periodicity. Physical properties of periodic hydrogel mesostructures are also described. |
