The flexible and shockproof rubber-based Al/OD-Gel/Cu electrochemical cell was designed, fabricated, and investigated for the detection of IR and UV irradiations. For this purpose, the transparent gel-orange dye composite was deposited on the porous rubber substrate between aluminum and copper electrodes. It was observed that the gel-orange dye composite was mechanically like a gel: soft and flexible. Electrically, this composite (gel-orange dye) forms a flexible electrolyte. It was found that the impedance of the samples under the effect of infrared irradiation decreased by 2.02 to 2.19 times on changing frequency from 100 Hz to 200 kHz. Accordingly, under the effect of ultraviolet irradiation, the impedance of the samples decreased by 1.23 to 1.45 times on increasing frequency from 100 Hz to 200 kHz. Under the effect of infrared irradiation up to 4000 W/m, the cell's open-circuit voltage increased by 1.59 times. The cell's open-circuit voltage also increased by 1.06 times under the effect of ultraviolet irradiation up to 200 uW/cm. The mechanism of the absorption of the infrared and ultraviolet irradiations by the OD-Gel composite has been discussed in detail. The fabricated flexible rubber substrate-based Al/OD-Gel/Cu electrochemical cells can be used as a prototype for the development of gel electronics-based devices.
设计、制造并研究了基于橡胶的柔性防震Al/OD -凝胶/Cu电化学电池，用于检测红外和紫外线辐射。为此，将透明的凝胶 - 橙色染料复合材料沉积在铝电极和铜电极之间的多孔橡胶基板上。观察到凝胶 - 橙色染料复合材料在机械性能上类似凝胶：柔软且有弹性。在电学上，这种复合材料（凝胶 - 橙色染料）形成一种柔性电解质。研究发现，当频率从100 Hz变化到200 kHz时，在红外辐射作用下样品的阻抗降低了2.02至2.19倍。相应地，在紫外线辐射作用下，当频率从100 Hz增加到200 kHz时，样品的阻抗降低了1.23至1.45倍。在高达4000 W/m的红外辐射作用下，电池的开路电压增加了1.59倍。在高达200 μW/cm的紫外线辐射作用下电池的开路电压也增加了1.06倍。详细讨论了OD -凝胶复合材料吸收红外和紫外线辐射的机理。所制造的基于柔性橡胶基板的Al/OD -凝胶/Cu电化学电池可作为开发基于凝胶电子器件的原型。
