SMOKING ARTICLE INCORPORATING A CONDUCTIVE SUBSTRATE

Abstract: the present invention provides a conductive substrate useful for joule heating, such as in an electronic smoking article. particularly, the invention provides a resistive heating element formed of a conductive substrate. the conductive substrate comprises an electrically conductive material and a carbonaceous additive, such as a binder material. the conductive substrate is carbonized in that it is subjected to calcining conditions to effectively reduce the carbonaceous additive to its carbon skeleton. it has been found that such carbonized substrate has surprisingly improved resistance properties in relation a substrate of the same formulation that is not carbonized. the carbonized substrate can include an aerosol precursor material. the formed resistive heating element can be included in an electronic smoking article to simultaneously provide resistive heating and aerosol formation with a single, unitary component.
