As an intelligent material, polymer gel is able to respond to external stimulus, including temperature, chemical
concentration, pH, etc. The theoretical framework of chemo-mechanical coupling behavior for intelligent polymer gel is
emphasized in this paper. Analytical solutions of the displacement and concentration function are found for one
dimensional chemo-mechanical coupling problem. It is shown that the present chemo-mechanical theory can be applied
to model chemo-mechanical coupling behavior of intelligent polymer gel. This study has important significance to reveal
the mechanism of chemo-mechanical coupling behavior of the polymer gel.
