“…96 A great number of studies on electrospun gas sensors have been published to date, and have been reviewed by Ding et al, 97 leading to a great variety in polymer materials used and types of gases which can be detected. One example of a common system is the use of polyacrylic acid (PAA) which can readily detect ammonia through interaction with the carboxyl groups on PAA.…”

“…Electrospun SnO 2 and MoO 3 nanowires show increased stability, faster response time, and higher sensitivity than thin film structures of the same materials in detecting H 2 S and NH 3 , respectively. 58 ZnO nanowires prepared in an electrospinning process have been used to detect ethanol vapor at concentrations as low as 10 ppm at 220 C. 59 WO 3 nanofibers behave as a semiconductor when heated and their electrical resistance varies when exposed to NO 2 gas. 60 TiO 2 /polyvinyl acetate composite nanofibers also show exceptional sensitivity to NO 2 when electrospun onto Pt electrodes.…”

Electrospinning of nanomaterial composites are gaining increased interest in the fabrication of electronic components and devices. Performance improvement of electrospun components results from the unique properties associated with nanometer-scaled features, high specific surface areas, and light-weight designs. Electrospun nanofiber membrane-containing polymer electrolytes show improved ionic conductivity, electrochemical stability, low interfacial resistance, and improved charge-discharge performance than those prepared from conventional membranes. Batteries with non-woven electrospun separators have increased cycle life and higher rate capabilities than ones with conventional separators. Electrospun nanofibers may also be used as working electrodes in lithium-ion batteries, where they exhibit excellent rate capability, high reversible capacity, and good cycling performance. Moreover, the high surface area of electrospun activated carbon nanofibers improves supercapacitor energy density. Similarly, nanowires having quasi-one-dimensional structures prepared by electrospinning show high conductivity and have been used in ultra-sensitive chemical sensors, optoelectronics, and catalysts. Electrospun conductive polymers can also perform as flexible electrodes. Finally, the thin, porous structure of electrospun nanofibers provides for the high strain and fast response required for improved actuator performance. The current review examines recent advances in the application of electrospinning in fabricating electronic components and devices.

“…Recently, Sawicka 35 , et al synthesised composite nanostrucrures consisting of polymer (PVP) and metal-oxide nanofibres/nanowires of MoO 3 /WO 3 using electrospinning technique. They observed that WO 3 nanofibres can be used as NO 2 gas-sensing elements and the results were superior in terms of sensitivity (Fig.…”

Recent discoveries indicate that when the materials are brought down to sizes in the range 1-100 nm, these exhibit unique electrical, optical, magnetic, chemical, and mechanical properties. Methods have now been established to obtain the monodisperse nanocrystals of various metallic and semiconducting materials, singlewalled and multi-walled nanotubes of carbon and other metallic and non-metallic materials together with organic nanomaterials such as supra-molecular nanostructures, dendrimers, hybrid composites with tailored functionalities. The high surface-to-volume ratio with an added element of porosity makes these highly potential candidates for chemical and biological sensor applications with higher degree of sensitivity and selectivity as compared to their bulk counterparts. The paper reviews the recent developments and applications of chemical and biological sensors based on nanomaterials of various structural forms.
