中文摘要:
      制备了一种利用结构色水凝胶作为导电电极的光电双响应传感器。以十二烷基衣康酸甘油酯(DGI)、十二烷基硫酸钠(SDS)、氯化钠等为原料,通过双分子层自组装的方法,制备了结构色凝胶。将这种结构色水凝胶与传统电容型传感器相结合,得到了光电双响应传感器。采用SEM、LCR数字电桥、拉力试验机、光纤光谱仪等对器件进行了结构、光学、电学及机械性能的表征。结果表明:传感器在拉伸状态(0~100%)和压缩状态(0~60.9 kPa)下,传感器的电容分别变化了31%和44%,其自身颜色在可见光光谱内可以动态可逆的从红色变化到紫色。经历15000次循环拉伸后,传感器性能依旧保持稳定。利用传感器颜色的刺激响应性,传感器在发生形变时,其表面可以清楚地显示出应变源的位置和形状。这样传感器在检测时就可以实现可视化效果。
英文摘要:
      A photoelectric double response sensor using a structured color hydrogel as conductive electrode was prepared. The structured color hydrogel was prepared by bilayer self-assembly method using dodecyl glyceride itaconate (DGI), sodium dodecyl sulfate (SDS), sodium chloride as raw materials. The photoelectric double response sensor was combined by structured color hydrogel and traditional capacitive sensor.SEM, LCR meter, Tensile testing machine, Fiber optic spectrometer were used to characterize the device structure, optical, electrical and mechanical performance. Results show that in the tensile state (0~100%) and the compressed state (0~60.9 kPa), the capacitance of the sensor changes by 31% and 44% respectively, and the color of the sensor can changes dynamically and reversibly from red to purple in the visible light spectrum. After 15,000 times of cyclic stretching, the performance of the sensor remains stable. By using the stimulus response of sensor's color, the surface of the sensor can clearly shows the location and the shape of the strain source when the sensor is deformed. So the sensor can realize visualization effect during detection.
