Abstract

We investigated the effects of physical aging on the bending recovery of polyester conductive films coated with Ag nanowires (AgNWs). The physical aging treatment contributed to the improvement in the bending recovery of polyester films irrespective of the AgNW coating. The stress relaxation-recovery experiment confirmed that the films with good bending recovery demonstrated retarded stress relaxation, increased instantaneous elastic strain, and decreased permanent deformation. The drying temperature after coating had an effect on the bending recovery of polyester films, with a significant effect on the poly(ethylene terephthalate) (PET) film that had a lower glass transition temperature compared to poly(ethylene naphthalate) (PEN) film. Physical aging did not significantly affect the electrical resistance of the AgNW-coated polyester films.
