Numerous studies have shown that the glass transition temperature, T-g, of polymers may change visibly upon addition of even small amounts of nanoparticles. In this study, we examine the effect of polymer-nanoparticle interfacial energy on this phenomenon in nanocomposite films containing polystyrene-...
An explicit equation for the glass transition temperature (Tg) of compatible polymer-diluent mixtures is derived from a comparison of classical and statistical thermodynamic relations of the excess entropy. The ratio of Tg for plasticized/unpiasticized systems is related to the ratio of ...
aGlass transition temperature (Tg). That temperature at which, upon cooling, a noncrystalline ceramic or polymer transforms from a supercooled liquid to a rigid glass. 玻璃转化温度 (Tg)。 在冷却,一个非晶形陶瓷或聚合物从超冷的液体变换到一块刚性玻璃的那个温度。 [translate] ...
G. PANAYIOTOU (15a) The suggestion of Gibbs and DiMarzio is that the entropy Sis becoming zero at the glass transition temperature. By adopting this sug- gestion, one can use eq 15 for the case of pure polymers and evaluate the flex energies 8i. Values of 8i along with equation-of-...
As a first step, in this paper, we investigate the glass transition temperature of a polyurethane SMP reinforced with treated/non-treated attapulgite in wet and dry conditions. In addition to confirming the strong influence of moisture, the results reveal that non-treated clay significantly reduces...
When a polymer is modified so that its glass transition temperature, Tg, is decreased (increased) from the inherent value, its dynamics is often supposed to be enhanced (suppressed). For polymer films, there is an ongoing debate about whether a change in Tg upon changing the film thickness ...
preference, while P2–P4 had both edge-on and face-on packing orientations with the fraction of face-on crystallites significantly increasing with molecular weight. Furthermore, the charge transport behavior was affected by the different crystallite orientations (Table1; Supplementary Fig.S4)43,45....
Glass TransitionNonionic SurfactantsEquilibrium colloid stability measurements with nonionic surfactant (C 12 E 8 ) stabilised polybutyl methacrylate ( PBMA ) latex dispersions indicate a sudden temperature induced destabilisation coinciding with the glass transition temperature, Tg , of the polymer.
