主 题：Temperature-sensitive hydrogels thermally controlled deformation swelling-induced bending
摘 要：The present work investigates the thermally controlled deformation characteristics in temperature-sensitive hydrogels *** free energy density for temperature-sensitive hydrogels is modified,upon which the finite element model is developed and implemented through user-defined material subroutine UHYPER in the commercial software *** modified UHYPER implementation allows for more vividly depicting the continuous deformation in phase temperature region for temperature-sensitive *** thermally controlled cases of temperature-sensitive hydrogel including grippers,self-folding boxes,thermally driven origami are presented to illustrate a wide array of complex interesting applications or ***,we develop a simple model to theoretically calculate the bending angle of the temperature-sensitive hydrogel bilayers,which has been validated by the finite element simulation *** study can provide more insights for optimal design in thermally controlled hydrogels structures.
