Abstract:
The results of an experimental study of the effect of mechanical bending on the conductivity of polymer nanocomposite films of polyvinyl alcohol (PVA) and polymethyl methacrylate (PMMA) with single-walled carbon nanotubes (CNTs) are presented. It is shown that with increasing bending (decreasing the radius of curvature), the resistance of the films increases to 20% of the initial values when the radius of curvature changes to 14 mm. In this case, the dependence of the change in film resistance on bending is not linear. The maximum change in resistance due to bending is observed in nanocomposite films with a CNT mass concentration of 0.5%. The results obtained can be used in the development of bending or strain sensors that can be easily manufactured using available materials, technological methods and equipment.
