Polyvinylpyrrolidone/polyaniline composite based 36° YX LiTaO3 Surface Acoustic Wave H2 gas sensor

Generally, non-conducting polymers such as Poly-vinyl-pyrrolidone (PVP) are defined as the polymers with high resistivity [1]. Although these type of polymers are useful for a variety of chemical sensor types, the use of PVP as the a sensing layer has been rarely reported. Recently, He at al. [2] ha...

Description
Summary:Generally, non-conducting polymers such as Poly-vinyl-pyrrolidone (PVP) are defined as the polymers with high resistivity [1]. Although these type of polymers are useful for a variety of chemical sensor types, the use of PVP as the a sensing layer has been rarely reported. Recently, He at al. [2] has electrospin-coated the PVP fibers onto the Surface Acoustic Wave (SAW) device and successfully functions as H 2 gas sensor. The work then extended by Chee et al. [3] by adding multiwall carbon nanotube (MWNT) to produce the composite of PVP/MWNTs fibers as H 2 gas sensor. By modifying the previous research, this work shows the gas sensing properties of PVP/polyaniline composite/36° YX LiTaO 3 SAW device.
