WebApr 12, 2024 · The lowest glass transition temperature was achieved at 6% doping of the filler into the polymer matrix. It was established that the thermal, morphological, and crystalline properties were tailored by synthesizing their nanocomposites with the mesoporous bio-nanocarbon obtained from coconut shells. WebNov 1, 2024 · The moisture sorption was in the order of HPC>HPMC>HPMCP>HPMCAS>EC, and there was no significant effect of the molecular weights of polymers on moisture uptake. There was also less moisture sorption at 40 °C than that at 25 °C. Glass transition temperatures (T g) of the polymers decreased with …
WebMelting and Glass Transition Temperature For amorphous and semicrystalline polymers, this is a critical aspect of designing with polymers. • Crystalline polymers: there is a discontinuous change in specific volume at Tm • Amorphous polymer: continuous, no Tm - but there is an increase in slope at Tg, the glass transition temperature,
WebApr 13, 2024 · The hysteresis peak on the non-reversing signal at the glass transition of poly (butylene terephthalate) after cooling at 1, 2, 5 and 10 °C min −1. Underlying heating rate 10 °C min −1, modulation ± 0.5 °C/40 s. The intensity of hysteresis peak increases with decreasing cooling rate. WebGlass-transition temperature (T g ) marks the temperature at which an amorphous polymer is cooled from the rubbery to the glassy state. As rheological, mechanical, and dielectric properties change dramatically when the operating temper- ature passes through T g , T gplays a vital role in a wide range of both scientific and industrial processes.
WebOne of the most important properties of the polymers is known as the glass transition temperature (T g), which measures chain mobility. This is a temperature at which a polymer transforms from a hard, glassy material to a soft, rubbery material. ...
