| Research Abstract |
Adhesion has attracted much attention because it is one of the most important processes for building functional constructs. In particular, several jointing methods have been reported for adhesion of the hard materials. To develop functional devices using stimuli-responsive hydrogels such as soft actuators6 and intelligent drug delivery systems, the adhesion of hydrogels is required. We studied a novel strategy for the adhesion of hydrogels. We present a technique using electrophoresis to deliver polyions inside of the gels and to form a polyion complex at the interface of the two hydrogels for adhesion. Moreover, detachment of the adhered hydrogels was possible by simply applying the inverse voltage.
