Melting behavior of polymer crystal formed during rapid cooling and/or low temperature annealing
Study of melting of original polymer crystals formed during rapid cooling and/or low temperature annealing becomes possible with the development of the very fast (over tens of Kelvin per second, K/s) scanning calorimeter.

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...

Characterization of electrospun polymer fibers using polarized infrared, scanning electron microscopy (SEM) and selected area electron diffraction (SAED)
Kakade et al. first reported that electrospun poly (ethylene oxide) fibers collected from gapped, counter electrodes are not only macroscopically aligned but also have polymer chains aligned parallel to the fiber axis.
