Abstrakt: | This contribution deals with preparation of functional interdigited flexible sensors for room temperature operation. The fabrication comprises the utilization of promising technology such as inkjet printing and the deposition of copper(II) acetylacetonate as a ultrathin sensing layer. The inks were prepared by dispersion formation in co-solvent system. The ink composition was developed on the basis of viscosity and surface tension optimization by the addition of polymeric steric surfactant. The printing process was optimized with the help of non-dimensional criteria. To obtain the best possible shape and resolution various parameters such as surface modification, thermal reduction atmosphere, annealing condition, setting of inkjet printer, Ink concentration and viscosity, sheet resistance were investigated. Printed pattern and motifs were characterized by profilometry, microscopy and by resistance measurement to further enhance the quality of printing. The sensitivity of the prepared sensors was demonstrated and studied by measuring the response to saturated vapors at room temperature to improve sensor performance by optimization. Obtained sensitivity of prepared sensors is very promising for detection of organic vapor detection at room temperature. Moreover, other big promising advantage of prepared sensors is their flexibility. © NANOCON 2019.All right reserved. |
