Shape transformation of hydro/organo Janus films: A hydro/organo Janus copolymer film has been designed and fabricated via a novel strategy, an unconventional one-step interfacial polymerization of the immiscible hydrophilic vinyl monomer solution and hydrophobic vinyl monomer solution. Under the binary cooperative effect of the hydrogel network and organogel network, the Janus film is able to work both in the aqueous solutions and organic solvents, and exhibit excellent shape-transformation performance, such as bidirectional and site-specific bendings.
