摘要

相对湿度是通过陶瓷、金属氧化物和聚合物传感器测量的工业过程中的主要参数。随着相对湿度的增加和烧结温度的升高,陶瓷和金属氧化物传感器表现出非线性电阻行为。聚合物传感器将陶瓷和金属传感器转变为聚合物传感器,其合成工艺环保,热强度小,灵敏度高。在这项研究工作中,利用纳米纤维氧化石墨烯合成了一种具有可持续捕获和电阻响应的增强电性能的聚合物传感器,用于感应湿度。将改进Hammer法合成的氧化石墨烯与聚乙烯醇(GO/PVA)以5 wt %的比例在90℃下混合4小时。在24V直流电场下得到氧化石墨烯和聚乙烯醇(GO/PVA)溶液的纳米纤维;0.5 ml/h的进料速率和10cm的电纺丝针尖到收集器的距离。将GO/PVA纤维沉积在8mm的银间指电极上,连续距离为20Îm的五梳。SEM分析表明纤维在纳米范围内,无大的裂纹,XRD和FTIR分别研究了GO和GO/PVA的指纹和官能团。在相对湿度为0% ~ 82%的范围内,分析了不同频率下电阻和电容的响应差异和恢复时间的参数研究。

Synthesis and characterization of nano-fibres graphene oxide for sensing humidity
Relative humidity is the prime parameter in industrial processes which are measured through ceramic, metal oxide and polymeric sensors. Ceramic and metal oxide sensors shows nonlinear resistive behaviours with increasing relative humidity and high sintering temperature for hydro-desorption. Transformation of ceramic and metallic sensors with the polymeric sensors is due to its eco-friendly synthesis fabrication, less heat intensive and high sensitivity. In this research work, a polymeric sensor of enhanced electric properties with sustainable captive and resistive response was synthesised from nano-fibres graphene oxide for sensing humidity. The synthesized graphene oxide through modified Hammer method was mixed with poly-vinyl alcohol (GO/PVA) in the ratio of 5 wt % for four hours at 90 ºC. Nano fibres of graphene oxide and poly-vinyl alcohol (GO/PVA) solutions were obtained at the 24V DC electric field; 0.5 ml/h feed rate and 10 cm tip-to-collector distance through electrospinnig. GO/PVA fibres were deposited on the silver inter-digited electrodes of 8mm and five combs of 20Îm consecutive distance. SEM analysis shows that the fibres were in nano-range with no major cracks while XRD and FTIR spectrum investigated the finger prints and functional groups of GO and GO/PVA respectively. Parametric study of resistive and capacitive were analysed at difference response and recovery time at various frequency in the range of 0 % to 82% relative humidity.
