报告内容:
Imidazolium-based ionic liquid surfactant monomers (surfmers) are stimuli-responsive to select anions and solvents, and provide basis for many useful polymers that also are stimuli-responsive as well as highly useful dispersion stabilizers. We illustrate the synthesis of various homopolymers, diblock copolymers, triblock copolymers, and nanolatexes that exhibit LCST, reversible nanoparticle formation, stimuli-responsive dewetting, osmotic brush stabilization by adsorption from solution and suspension, stimuli-responsive destabilization and controlled coatings of submicron graphene platelets, and stimuli-responsive phase transfer. We also illustrate the first example of reversible photonic crystal crystallization based on enthalpic rather than entropic driven free energy changes in a lyotropic nanogel system.
