Diblock copolymers have received considerable attention because of their micro-phase separation behavior in solid phase and self-assembly to form nano objects in solutions.  We have prepared cellulosic diblock copolymers with regioselective functionalization patterns.  Aqueous solutions of diblock methylcellulose and its analogues have exhibited lower critical solution temperature (LCST) under body temperature, thereby forming thermo-responsive hydrogels.  We found that ribbon-like supramolecular nanostructures played critical roles in the formation of thermo-responsive hydrogels.  The talk will include a versatile pathway to end-functionalized cellulose ethers, their solution properties, and some applications of the thermo-responsive hydrogels.
