Abstract

A simple, effective strategy was developed and demonstrated to prepare thermosensitive poly(N-isopropylacrylamide) (PNIPAAm) hydrogel with a superfast response by using an organic solvent, tetrahydrofuran (THF), as a foaming agent as well as a precipitation agent during the polymerization/crosslinking in water at room temperature. The superfast response PNIPAAm hydrogel was attributed to the macroporous network and heterogeneous matrix, and it may contribute significantly to the construction of novel intelligent devices in the future.
