Heating Characteristics of Transparent Films Prepared with Conductive Composite Materials

Transparent heating film was fabricated with the conductive coating solution including silver nanowire and graphene oxide. Visible transmittance, electric resistance, and heating temperature were analyzed on the as-prepared film. Transparent heating film was fabricated with a resistance value of 100 Ω or less, and the visible transmittance was adjusted at a level of 90% or less according to the loading of Ag nanowire. The heating temperature was stably increased throughout the film up to 100 °C or more in proportion to the applied DC voltage.
