A lamellar hydrogel with high toughness, exhibiting ternary stimuli-responsive structural color changes has been synthesized. The gel consists of alternating hard layers of a polymeric surfactant (PDGI) and soft layers of interpenetrating networks of poly(acrylamide)-poly(acrylic acid). Reversible, wide range switching of the stop-band position was achieved using different external stimuli of temperature, pH, and stress/strain.
一种具有高韧性的层状水凝胶,表现出三元刺激响应结构颜色变化,已经被合成。该凝胶由交替的聚合物表面活性剂(PDGI)硬层和互穿聚合物网络的聚丙烯酰胺-聚丙烯酸软层组成。使用不同的外部刺激,如温度、pH 值和应力/应变,可以实现停带位置的可逆、宽范围切换。
