Description
Summary:Anisometric microgels are prepared via thermal crosslinking using an in-mold polymerization technique. Star-shaped poly(ethylene oxide- stat -propylene oxide) polymers, end-modified with amine and epoxy groups, form hydrogels, of which the mechanical properties and gelation rate can be adjusted by the temperature, duration of heating, and polymer concentration. Depending on the microgel stiffness, the rod-shaped microgels self-assemble into ordered or disordered structures. Star-shaped poly(ethylene oxide- stat -propylene oxide) polymers are end-modified with amine and epoxy groups to produce anisometric microgels with adaptable mechanical and (bio)chemical properties and self-assembly behaviour.
