To implement polymer sensing materials, however, the fabrication capability and stability are major concerns. In this work, an inkjet printable humidity sensing material, poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS), is developed to improve the fabrication capability. Besides, different kinds of nanoparticles, SiO2 and aluminum zinc oxide (AZO), are also employed to enhance the stability and sensitivity to humidity sensing. Based on experimental results, the sensitivity can be improved by 100%; the stability can also be noticeably enhanced. To understand the sensing mechanism, X-ray diffraction (XRD), Fourier transforms infrared diffraction (FTIR), and photoluminescence (PL) spectrometer measurements are performed. Based on these material investigations, the sensing enhancement is due to physical adsorption of the blending nanoparticles. This work proposes a high sensitivity and low cost humidity sensing material for different applications. © 2013 The Japan Society of Applied Physics. |
