摘要

研究了以过氧乙酸和纳米纤维素为溶剂，通过对芒草有机溶剂浆的水解法制备芒草秸秆纤维素的环保方法。研究了纳米纤维素的性能及其在电容式和电阻式湿度传感器中的应用。研究了电极参数和工作频率对传感器特性的影响。实验结果表明，器件灵敏度随电极间距和工作频率的减小而增大。基于纳米纤维素的电容式和电阻式湿度传感器的响应范围分别为1.15 ~ 102 nF和5.1 *101 ~ 1.1 *103 nF。灵敏度最大值可达0.094 (%RH)−1。

Flexible Humidity Sensors Based on Nanocellulose

The study describes methods for preparing cellulose from miscanthus stalks in an environmentally friendly way using a solution of peracetic acid and nanocellulose by the method of hydrolysis of organosolv miscanthus pulp. The properties and application of nanocellulose in capacitive and resistive humidity sensors have been studied. We have investigated influence of electrode parameters and operating frequency on sensor characteristics. It was determined that device sensitivity increases with decreasing of the distance between electrodes and operating frequency. The responses of capacitive and resistive humidity sensors based on nanocellulose were in the range of 1.15 - 102 nF and 5,1*101 - 1,1*103 correspondingly. The maximum value of sensitivity was reached up to 0,094 (%RH)−1.
