Acetone Sensing Properties of NiO Nanofibers Based on Electrospinning

Abstract

Acetone is a main respiratory marker for diabetic patients. In this paper, P-type NiO nanofibers were prepared by electrospinning and used for the detection of acetone gas. NiO nanofibers were characterized by SEM and XRD. The uniform NiO nanofibers with face-centered cubic structure was obtained. The working temperature of NiO nanofibers was optimized, and the optimal operating temperature is 220°C. The response-recovery curve was tested, and the response and recovery time is 24.6 s and 610 s respectively. The response to different concentrations of acetone was also analyzed, and the detection limit was 100 ppb. These results show that NiO nanofibers based on electrospinning have potential applications in the respiratory testing of diabetes.

Carbon/NiO Compositional Fibers

“…Thus, due to the unique electrochemical characteristics of NiO, composite materials based on it can be used in various gas sensitive systems. For example, Fan X. et al [15] note the possibility of using a p-type composite based on NiO as a sensor for detecting gaseous acetone. Experimental results showed that the applied composite had an optimum sensor op-erating temperature in the range of 220 °C and sensitivity to acetone concentration of 100 bbp (parts per billion).…”

Investigation of the mechanical properties and biocompatibility of planar and electrospun alkene-styrene copolymers against P(VDF-TrFE) and porcine skin: Potential use as second skin substrates

“…Electrospun nanofibers typically display tensile strengths below 300 MPa and Young's moduli below 3 GPa Yao et al, 2014). P(VDF-TrFE) copolymers typically have Young's moduli of approximately 1.5 GPa when made in films, while fibrous structures may have Young's modulus values as low as 6.0±2.0 MPa (Fang et al, 2010;Bhavanasi et al, 2015;Fan et al, 2015). As such, this material was expected to mimic skin's properties to some extent.…”
