A simple spray coating process can be utilized to create epoxy/HNT nanocomposites with vertically aligned nanotubes. Important mechanical properties such as modulus and hardness values can be optimized and enhanced by controlling the level of nanotube dispersion during processing and the final orientation of the nanotubes. Thus, a technologically relevant processing scheme can be used to fabricate HNT nanocomposites with a high level of control over nanotube alignment and the resulting mechanical properties.

An object of this invention is to create an actuator in which the amount of deformation is maintained and no displacement in the reverse direction occurs, even when a constant voltage is continuously applied for a long period of time. As a means for achieving the above object, the invention provides a conductive thin film comprising a polymer gel containing at least one organic molecule selected from the group consisting of electron-donating organic molecules and electron-withdrawing organic molecules, a nano-carbon material, an ionic liquid, and a polymer.
