Abstract

Abstract Continuous porous poly(N-isopropylacrylamide) (pNIPAM) gels were prepared by radical polymerization in a bicontinuous microemulsion (BME) consisting of saline and toluene microphases. The BME gels demonstrated good thermoresponsive water swelling–shrinking performance, exhibiting high speed and large volume change compared with those of homogeneous pNIPAM gels. The BME gels also exhibited swelling with toluene, while the homogeneous pNIPAM gels could not be swollen with toluene.
