We investigated the effects of physical aging on the bending recovery of polyesterconductive films coated with Ag nanowires (AgNWs). The physical aging treatment contributedto the improvement in the bending recovery of polyester films irrespective of theAgNW coating. The stress relaxation-recovery experiment confirmed that the films withgood bending recovery demonstrated retarded stress relaxation, increased instantaneouselastic strain, and decreased permanent deformation. The drying temperature after coatinghad an effect on the bending recovery of polyester films, with a significant effect on thepoly(ethylene terephthalate) (PET) film that had a lower glass transition temperature comparedto poly(ethylene naphthalate) (PEN) film. Physical aging did not significantly affectthe electrical resistance of the AgNW-coated polyester films.
