Ambient Conditions

Polymer micelles were formed using thiol-epoxide “click” chemistry to trigger functionalization-induced self-assembly (FISA) of block copolymers by modifying a reactive glycidyl methacrylate block with solvophobes.

Novel block copolymers bearing a phthalocyanine were synthesized via atom transfer radical polymerization and “click” chemistry. Self-assembled nanoarchitectures are obtained through microphase separation of the block copolymers and phthalocyanine π–π interactions.

AbstractTriblock copolymers have traditionally been synthesized with conventional organic components. However, triblock copolymers could be synthesized by the incorporation of two incompatible protein-based polymers. The polypeptides would differ in their hydrophobicity and confer unique physiochemical properties to the resultant materials. One protein-based polymer, based on a sequence of native elastin, that has been utilized in the synthesis of biomaterials is poly (Valine-Proline-Glycine-ValineGlycine) or poly(VPGVG) [1]. This polypeptide has been shown to have an inverse temperature transition that can be adjusted by non-conservative amino acid substitutions in the fourth position [2]. By combining polypeptide blocks with different inverse temperature transition values due to hydrophobicity differences, we expect to produce amphiphilic polypeptides capable of self-assembly into hydrogels. Our research examines the design, synthesis and characterization of elastin-mimetic block copolymers as functional biomaterials. The methods that are used for the characterization include variable temperature 1D and 2D High-Resolution-NMR, cryo-High Resolutions Scanning Electron Microscopy and Differential Scanning Calorimetry.
