For environmentally friendly applications, the impact of Multi walled Carbon nanotubes (MWCNTs) on the optical and structural characteristics of a polyvinyl alcohol (PVA) blend has been investigated in this work. PVA blends loaded with MWCNTs (0 to 3% weight per cent) were equipped using the spin coating method. These movies were then analyzed using a variety of methods. These film samples underwent AFM and UV-visible analysis. The surface morphology of thin films was investigated using the atomic force microscope (AFM) technique. The results unequivocally demonstrated the similarity of the created films. The concentration of (MWCNTs) enhanced the average grain diameter, roughness and Root Mean Square (RMS) value. When MWCNT content is raised to 3 weight per cent, the direct energy gap of the composite blends decreases from 4.181 to 4.167 eV, according to UV-visible analysis. We investigate the effects of MWCNT amounts on the optical properties of different mixes. This study advances the continuous development of Nano composites, particularly by improving the gas sensor’s increased sensitivity.
