Role of Electrospun Zno-Nio Metaloxide Nanocomposite Fibers for Sensor Applications

Abstract:

Nowadays, Electro-spinning has gained an increased attention towards gas sensing material, battery and solar cells. Among the other one dimensional nanostructures, nano-fibers have an advantage of large surface to volume ratio, long axial ratio, large porosity and good mechanical properties. The metal oxides are extremely important technological materials for use in electronic and photonic devices. Electrospinning method is well due to its easier performation and mass production of fibers and variety of applications in various fields. This paper describes about the sensing studies of zinc oxide and nickel oxide  nanocomposite fibers prepared by electro-spinning method. Polyvinyl Alcohol  is used as a polymer to form fibers of zinc oxide and nickel oxide nanocomposite which was deposited on the glass substrate at room temperature . The basic characterization studies and gas sensing studies of as-spun fibers on formaldehyde and ammonia were studied.
