Photoreversible control of coumarin driven hydrophobic Ti3C2Tx MXene composite

In this study, a Ti3C2Tx MXene/coumarin (MC) composite has been designed and fabricated by the electrostatic self-assembly of the photoreversible coumarin-surfactant and Ti3C2Tx MXene, which exhibits an effective photoreversible performance. The structure of the MC composite transforms between the pleated and 3D undulating structures on irradiation with the 365/254 nm light for many cycles, thus, resulting in the conversion of the wettability...
