Poly(N-isopropylacrylamide) (PNIPAM) is broadly applicable in many fields due to its temperature-induced
phase transition property. Herein, a facile method to incorporate exfoliated Ti2C3Tx nanosheets in the
PNIPAM network is reported. Due to compatibility, stability and photothermal properties of the incorporated
Ti2C3Tx nanosheets, the obtained MXene/PNIPAM composite hydrogel shows excellent photothermal
properties, expanding the pure thermal-responsive property of the PNIPAM hydrogel. Based on
the smart composite hydrogel, remote light-control of the microfluidic pipeline is also demonstrated.
