Photo-responsive materials have received great attention, because light enables physically non-contact operation, independent local control and fast switching. Here, we have developed light-responsive hydrogels with temperature responsive hydrogels and graphene oxide which converts low intensity visible light to heats. In this materials system, degree of volume change of hydrogels could be simply controlled by light intensity, irradiation time, and graphene oxide feeding ratio. Furthermore, local volume change was observed induced by light irradiation of selected region. |
