Abstract
The present disclosure provides an aerosol source member and an aerosol delivery device that includes an aerosol source member. The aerosol source member includes a segmented substrate portion that includes a first substrate segment and a second substrate segment. The first substrate segment includes a first aerosol former, the second substrate segment includes a second aerosol former different from the first aerosol former, and the second substrate segment is positioned between the first substrate segment and a downstream end of the aerosol source member. The first substrate segment and the second substrate segment are configured such that when heated by a heat source, the first substrate segment is heated to a first temperature and the second substrate segment is heated to a second temperature that is less than the first temperature.
