Effect of UV/ozone treatment on surface hydrophilicity and humidity sensing properties of PVDF-BaTiO3 composite films
(
Qatar University Press
, 2021 , Poster)
In this research work, we have studied the impact of UV/ozone treatment on the hydrophilicity of the PVDF-BaTiO3 nanocomposite film. We have prepared the nanocomposite solution by mixing PVDF (2.5 wt% kept constant) and ...
Liquid exfoliated MoS2 sheet coupled with conductive polyaniline for gas sensor
(
Qatar University Press
, 2021 , Poster)
Polyaniline (PANI)/MoS2 composites with porous microspheres were prepared by a hydrothermal and in situ polymerization method. The structural, optical, and morphological properties were characterized by X-ray powder ...
