020. Free surface-induced glass-transition temperature suppression of simulated polymer chains
Glass-transition temperatures (Tgs) in poly-(ethylene oxide) chains of 250 monomers as typical examples have been extensively simulated with the systematically coarse-grained potentials. The studied model systems include two 1-chain systems without and with the periodic boundary condition and two 8-chain systems in the NVT and NPT ensembles, which are labeled as nopbc, pbc, NVT, and NPT, respect...

Effect of interface on bulk polymer: control of glass transition temperature of rubber
In current paper, we demonstrated that molecular dynamics and glass transition of rubber can be controlled by constructing attractive interface between rubber matrix and fillers. Based on a combination of experiments and molecular simulations, it was revealed that interfacial segmental mobility was reduced and glass transition temperatures (Tgs) of epoxidized natural rubber (ENR) were significantl...

Effect of monomer structure on crystallization and glass transition of flexible copolyesters.
Biodegradable amorphous flexible (co)polyesters with low glass transition temperature (Tg) are very desirable in some specific biodegradable applications like impact modification of brittle polymers and synthesis of elastomers. However, most biodegradable flexible polyesters and binary copolyesters made from diacid(s) and diol(s) are crystalline polymers. In order to...

37. A Stimuli-Responsive Hydrogel with Reversible Three-State Transition Controlled by Redox Stimulation
A great extent of past work has focused on the development of stimuli-responsive hydrogels that can primarily achieve a two-state transition, such as sol-gel translation. In the current work, a reversible hydrogel with three-state transition is designed. The three transformations between original, oxidized, and reduced states are achieved via controlling the external stimuli conditions. Hy...

Conformational Identification and Phase Transition Behavior of Poly(trimethylene 2,6-naphthalate) α?Form Modification
Poly(trimethylene 2,6-naphthalate) (PTN) is one of the 1,3-propanediol (PDO)-based aromatic polyesters which has potential applications for special barrier films and
packaging due to its excellent oxygen and carbon dioxide gas barrier property. In this work, we investigated the chain conformation and phase transition behavior of poly-
(trimethylene 2,6-naphthalene) (PTN) α-form crystal with synch...

007. Simulated glass transition of poly(ethylene oxide) bulk and film: a comparative study
Stepwise cooling molecular dynamics (MD) simulations have been carried out on the bulk and film models for poly(ethylene oxide) (PEO) to understand glass transition of amorphous polymer films. Three types of properties—density, energy, and dynamics—are computed and plotted against the temperature for the two systems. It has been confirmed that all these properties can reveal&nbs...

Method to Probe Glass Transition Temperatures of Polymer Thin Films
A new methodology was developed to probe glass transition temperatures (Tgs) of polymer thin films supported on gold (Au) substrates and confined between two solid (silica and silver) surfaces based on the surface plasmon polariton (SFPP) signals generated by sum frequency generation (SFG) spectroscopy. The measured Tgs for polymer (poly(methyl methacrylate), poly(b...
