摘要：

Iridescent crystalline hydrogels with high polymer concentration were synthesized by initiating crystallization of a colloidal fluid near the melting point but stabilizing the crystalline structure below the glass-transition temperature under the guidance of a phase diagram. The iridescent colors of such hydrogels shift from blue to red as the polymer concentration decreases from 5.4 to 3.5 wt% in water, as shown in the photographs.
