| 摘要:本研究通过纤维素纳米晶体(CNC)、姜黄素(Cur)和氯化胆碱/甘油低共熔溶剂(DES)协同组装,制备了一种兼具结构色、荧光和圆偏振发光特性的多重刺激响应膜(CNC/Cur/DES膜),并对其结构、力学性能、光学性能及刺激响应行为进行了研究。结果表明,DES的引入有利于调控CNC胆甾相结构,赋予CNC/Cur/DES膜良好的柔韧性(断裂伸长率(1.77±0.31)%)和圆偏振发光性能。CNC/Cur/DES膜能够实现结构色与荧光信号的协同输出,并对pH、乙醇和Fe3+等外界刺激产生明显的光学响应,表现出良好的可视化识别能力。 |
| Abstract:A multi-stimulus-responsive film with structural coloration, fluorescence, and circularly polarized luminescence (CPL) performance was fabricated through the co-assembly of cellulose nanocrystals (CNC), curcumin (Cur), and choline chloride/glycerin deep eutectic solvent (DES). The structure, mechanical properties, optical properties, and stimulus-responsive behaviors of the prepared CNC/Cur/DES film were systematically investigated. The results showed that the incorporation of DES effectively regulated the chiral nematic structure of CNC, endowing the film with good flexibility (fracture strain of (1.77±0.31)%) and CPL performance. The CNC/Cur/DES film enabled the synergistic output of structural color and fluorescence signals and exhibited distinct optical responses to various external stimuli, including pH, ethanol, and Fe3+, demonstrating excellent visual recognition capability. |
