In the present work, structural, optical, electrical and sensing properties have been studied for the (TiO2/rGO) nanocomposite prepared by the pulse laser ablation method in the liquid, where the Nd-Yag laser was used, and the two wave pulses (1064-532) and 300mJ, which were deposited on glass bases , The structural properties have been investigated by X-Ray diffraction technique analysis and morphological by atomic force microscope (AFM), The particle size of the membranes is less in the films prepared using wavelength (1064) than in the prepared films using wavelength (532). The optical properties of the nanocomposites have been determined by using the optical transmittance measurements in the spectral region from (300- 1100) nm. Electrical properties such as I-V properties were also studied. sensing properties measurements showed good Humidity sensitivity within the range (20-80) RH.
