Abstract Phase transition of hydrogel, which is polymerized by polymer network, can be
regarded as the transition of polymer network stability. The stability of the polymer
network might be changed when the external environment changed. This change will lead
to the transformation of sensitive hydrogels stability, thus phase transition of hydrogel
take place. Here, we present a new free density energy function, which considers
the non-gaussianity of the polymer network, chains entanglement and functionality of
junctions through adding Gent hyplastic model and Edwards-Vilgis slip-link model to
Flory-Huggins theory. A program to calculate the phase transition temperature was written
based on new… More >
