New generation of α-MnO2 nanowires @PDMS composite as a hydrogen gas sensor

New hydrogen gas sensor has been prepared by α-MnO 2 nanowires in polydimethylsiloxane matrix. For this purpose, the high aspect ratio α-MnO 2 nanowires has been prepared by the aid of hydrothermal method and then dispersed into poly-dimethyl siloxane polymer media. For gas sensing, the samples have...

Description
Summary:	New hydrogen gas sensor has been prepared by α-MnO 2 nanowires in polydimethylsiloxane matrix. For this purpose, the high aspect ratio α-MnO 2 nanowires has been prepared by the aid of hydrothermal method and then dispersed into poly-dimethyl siloxane polymer media. For gas sensing, the samples have been exposed under different gas concentrations from 0 to 5%. The sensor responses have been examined by normalized ellipsometric parameter with respect to the chamber filled with N 2 Gas. Our results indicate linear behavior of resonance wavelength in ellipsometric parameter as a function of gas concentrations which can open a new insight for the sample’s capability to hydrogen gas sensing applications.
