Background: Carbon nanotubes (CNT) synthesized by CVD method at 950 ℃. CNT and metal ZnO nanocomposites material synthesized by ball mill procedure have been examined. Stability of nanocomposite material has been attained by cationic ion liquid (IL), 1-tetradecyl-3 methylimidazolium chloride, structural morphology material characterized by Fourier transform infrared (FTIR) spectroscopy, Field emission scanning electron microscopy (FESEM), Ultraviolet visible (UV-Vis) spectroscopy. Furthermore, these materials were analyzed by Energy dispersive X-ray spectroscopy (EDX) to study for the percentage of elemental compositions. Current-Voltage (I-V) characterized by electrical properties are showing highly responsive of resistance variation and easy recoverable high sensitivity was the main feature of the CO2 gas sensing properties. Objective: Carbon nanotube and zinc oxide nanoparticle combined with different ratio and optimization of coating methods using for sensor applications. Methods: It is synthesized with chemical vapour deposition method and zinc nanoparticle developed by ball mill method. We have optimized spin coating and dip coating method on glass surface. Results: FTIR spectrum results are recommended that the existing hydroxyl group and C group CNT-ZnO nanoparticle covered by the surface active site of ZnO. The size and composition of the CNT-ZnO were confirmed by FESEM EDAX studies. The absorption and transmittance wavelength of CNT-ZnO nanoparticle were recorded by UV-Visible spectroscopy. The I-V property shows that the drain current and voltages are varied by gas implying the materials suitable for applications. Conclusion: This module can be used to monitor CO¬2 gas application instruments with help of software. In future, this module and techniques can be used to study stress sensor and piezoelectric applications |
