Abstract Nanocomposites of polypyrrole/reduced graphene oxide (PPy/rGO) and polypyrrole/ functionalized reduced graphene oxide with aryl 4-carboxybenzene diazonium salt (PPy/rGO-aryl-COOH) were prepared through covalent bonding by simple one-step chemical oxidative synthesis. The as-prepared nanocomposites were deposited on BOPET substrate by spin coating to test their chemiresistive sensitivity properties on a homemade modular for online detection of (NO2) vapors at ambient temperature. Results showed that PPy/rGO-aryl-COOH forms a homogeneous nanocomposite within the size of 80 nanometers and improvement of the crystalline ordering. The more enhanced NO2 sensing properties have been shown by PPy/rGO- aryl-COOH in terms of higher sensitivity (1.01%/ppm), the faster response time (129 s), and the detection limit of (2ppm). Reproducibility features were also investigated.Moreover, humidity rates and temperature effects were also tested. Finally, impedance spectroscopy is conducted in the fresh air and in the presence of gas. These results highlight the paramount role of functionalization of reduced graphene oxide (rGO-aryl-COOH).

This work describes the consequence of graphene oxide on the paddle shaped cantilever structure for the measurement of humidity in oil condition monitoring .The oxides present in the graphene has an significant effect in absorbing the content of water that available in the earth. The model for humidity sensor is designed and simulated using comsol Multiphysics. Various structures were simulated and the best structure is chosen for designing the humidity sensor. Graphene oxide was chemically synthesized from graphite powder. Thin film of GO was deposited on Aluminium substrate using spin coating. Various materials were analysed and the best material is coated on the substrate for humidity sensing. The samples were characterized using Scanning electron Microscope and Xray Diffraction methods. The sensitivity is ten times better than the conventional humidity sensor. The response time is fast less than ¼ of the conventional type. The recovery time of the graphene oxide based humidity sensor is also less than ½ of the conventional one.
