Abstract
The present disclosure relates to aerosol delivery devices, methods of forming such devices, and elements of such devices. In some embodiments, the present disclosure provides substrates for use in storing an aerosol precursor liquid and/or transporting the liquid to a heater for vaporization. The substrates can be formed form fibers that can provide improved absorbency and/or transport qualities. Multi-layer substrates are also disclosed and can include a high absorbency layer and a hydrophobic layer.
