a Photos of light propagation through THFOW in water under different temperatures (48 °C and 52 °C); (b) Photos of the light propagate through the THFOW with a segment of THFOW heating up and getting cool in sequence; (c) Light intensity variation during the cyclic heating and cooling of the THFOW segment; (d) Temperature-dependent 1H NMR spectra of (N70D30)50 hydrogel in D2O from 31 to 61 °C with an increment of 3 °C; (e, f) Schematic illustration of the thermosensitivity of the THFOW.
