AB - <p style="text-align: justify;">A biphase mixture continuum mechanics model is derived for neutral heat-shrinkable
thermo-sensitive hydrogels in this paper. The mixing free energy of the
special mixture is recalculated based on the partition function of Bose system, and it
evaluates the contribution of the hydrophilic, hydrophobic interaction and hydrogen
bonding to the volume phase transition behaviors. The ideas of the Flory lattice theory
and the UNIFAC group contribution method are employed to get the expression of the
mixing free energy. Then we deduce a particular model by combining this mixing free
energy with the conservation laws equations and constitutive relations of both phases
to predict the volume transition behaviors of these special hydrogels.</p>
