Hydrogels are reticular polymer compounds containing a large number of hydrophilic groups. Under the stimulation of external physical and chemical factors, such as temperature, pH, light, electricity, magnetism, sound, force and chemical solution, reversible changes in volume and shape can occur under artificial control. Compared with other types of hydrogels, electrosensitive hydrogels are mostly composed of polyelectrolyte polymers, which can deform under the action of DC electric field. Realizing the conversion of electrical energy to mechanical energy, it can be applied as an energy conversion device in fields such as robots, sensors, controllable drug release, and artificial muscles. In this paper, based on the chemical mechanical electrical continuum model of electrosensitive cantilever hydrogel proposed by Abdolhamid[1], the evolution process of bending behavior of electrosensitive hydrogel under external electric field stimulation is studied. The bending deformation of electrosensitive hydrogels with different electric stimulation, concentration of the mobile ions in solution and bound anions concentration of gel was studied. The results show that the size of the potential, the concentration of mobile ions in the solution and the concentration of bound anions in the gel will have a greater impact on the bending deformation of the electrosensitive hydrogel. The conclusions obtained have certain guiding significance for the design and manufacture of the electrosensitive hydrogel.
Shape memory polymer (SMP) has been applied in many fields as intelligent sensors and actuators. In order to improve
the mechanical properties and recovery force of SMP, the addition of minor amounts of carbon nanotubes (CNT) into
SMP has attracted wide attention. A micromechanical model and thermo-mechanical properties of CNT/SMP composites
were studied in this paper. The thermo-mechanical constitutive relation of intellectual composites with isotropic and
transversely isotropic CNT was obtained. Moreover, the shape memory effect of CNT/SMP composites and the effect of
temperature and the volume fraction of CNT were discussed. The work shows that CNT/SMP composites exhibit
excellent macroscopic thermo-mechanical properties and shape memory effect, while both of them can be affected
remarkably by temperature and the microstructure parameters.
