摘要

A nonionic poly(oxyethylene) monoalkyl ether (C12(EO)6) and a cationic hexadecylpyridinium bromide (HPB) were used to achieve warm/cool transparency transition switchability, depending on the decrease in the hydration of the EO-headgroup of C12(EO)6 above the cloud point (Tc) and the crystallization of HPB below the Krafft point (Tk). The liquid state shows the advantage of being free-flowing, frost-resistance, flexible-adjustment and solar-energy-storing-capability due to the moisture-rich characteristics, while the hydrogel state exhibits free-standing properties.
