The switching of NIPAM/bentonite in KPS aqueous solution. (a) Describes the switching of NIPAM/bentonite in KPS aqueous solution; (b) shows the transmittance of NIPAM/bentonite in KPS aqueous solution at various temperatures; (c,d) respectively show the characteristic peaks of NIPAM/bentonite composite before excitation (at 20 °C) and after excitation (at 70 °C) in FTIR and XRD analysis; (e,f) respectively describe the particle size of NIPAM/bentonite in KPS aqueous solution at 20 °C and 70 °C; while (g) shows the particle size of excited NIPAM/bentonite at 40 °C.
