Recent progress in shape memory polymer: New behavior, enabling materials, and mechanistic understanding
Qian Zhao,H. Jerry Qi,Tao Xie +2 more
TL;DR: Progress in new shape memory enabling mechanisms and triggering methods, variations of in shape memory forms (shape memory surfaces, hydrogels, and microparticles), newshape memory behavior (multi-SME and two-way-S ME), and novel fabrication methods are reviewed.
Journal ArticleDOI
Structural Relaxation of Polymer Glasses at Surfaces, Interfaces, and In Between
TL;DR: The glassy-state structural relaxation of polymers near surfaces and interfaces by monitoring fluorescence in multilayer films is analyzed, finding that the distribution in relaxation rates extends more than 100 nanometers into the film interior, a distance greater than that over which surfaces and interface affect the glass transition temperature.
Journal ArticleDOI
Challenges and opportunities for mixed-matrix membranes for gas separation
TL;DR: In this article, a review of major challenges surrounding mixed-matrix membrane (MMM) and strategies to tackle these challenges are given in detail, and major models for separation performance prediction of MMM are reviewed in terms of their interrelations and limitations.

The Temperature Dependence of Relaxation Mechanisms in Amorphous Polymers and Other Glass-Forming Liquids
Journal ArticleDOI
On the Temperature Dependence of Cooperative Relaxation Properties in Glass‐Forming Liquids
Gerold Adam,Julian H. Gibbs +1 more
TL;DR: In this paper, a molecularkinetic theory was proposed to explain the temperature dependence of relaxation behavior in glass-forming liquids in terms of the temperature variation of the size of the cooperatively rearranging region.
Journal ArticleDOI
Non-symmetrical dielectric relaxation behaviour arising from a simple empirical decay function
Graham Williams,David C. Watts +1 more
TL;DR: In this article, the empirical dielectric decay function γ(t)= exp −(t/τ 0)β was transformed analytically to give the frequency dependent complex dielectrics constant if β is chosen to be 0.50 in the range log(ωτ0) > −0.5.

Analysis of recent measurements of the viscosity of glasses
TL;DR: In this article, the authors compared the results given by English with those of Washburn, Shelton and Libman, indicating a discrepancy in the absolute values of log10 viscosity amounting to 0.6.
