Kinetics of coil-to-globule transition of dansyl-labeled poly(n-isopropylacrylamide) chains in aqueous solutions
The coil-to-globule transition of thermally sensitive linear poly(N-isopropylacrylamide) (PNIPAM) labeledwith dansyl group was induced by 1.54-μm laser pulses (width ~ 10 ns). The dansyl group was used to follow thetransition kinetics because&n...

Tuning the glass transition temperatures of polymers by up to 100℃: equivalence of confinement effects in multilayer films and polymer blends
The glass transition of a polymer occurs when, upon cooling, chains are no longer able to adopt equilibrium conformations on the experimental time scale. This transition from a disordered, rubbery or liquid equilibrium state to&nb...
