Novel conveyer gels exhibiting autonomous peristaltic motion without external stimuli were prepared by copolymerizing temperature-responsive N-isopropylacrylamide (NIPAAm), ruthenium tris(2,2’-bipyridine) (Ru(bpy)₃) as the catalyst for the Belousov-Zhabotinsky (BZ) reaction and 2-acrylamido-2-methylpropanesulfonic acid (AMPS). The prepared bulky gel had an aggregative structure of its microgels when the AMPS feed ratio was low due to the effect of the poor solvent in the polymerization process. That structure highly improved the swelling-deswelling kinetics and generated swelling-deswelling amplitude more than 10% of the gel thickness, which was approximately 10 times larger than that of the gel with a homogeneous network structure. Further, we attempted to transport an object by utilizing the peristaltic motion of poly(NIPAAm-co-Ru(bpy)₃-co-AMPS) gel. A cylindrical poly(acrylamide) (PAAm) gel was transported as a model object on the poly(NIPAAm-co-Ru(bpy)₃-co-AMPS) gel surface wave when the gel had the aggregative structure of its microgels.
