description Optically transparent, conductive, and mechanically flexible epoxy thin films nanocomposite are produced in the present study. Investigations on the properties of different epoxy/hardener ratios, two different aspect ratios of multiwalled carbon nanotubes (MWCNTs) and MWCNTs loading in epoxy were carried out.

It was shown that the specimens with an epoxy-to-hardener ratio of 100: 45 (Systems A) exhibit higher tensile strength, Young’s modulus and storage modulus compared to an epoxy-to-hardener ratio of 100: 60 (System B).
