摘要： The present invention provides a conductive substrate (50) useful for Joule heating, such as in an electronic smoking article (10). Particularly, the invention provides a resistive heating element formed of a conductive substrate (50). The conductive substrate (50) comprises an electrically conductive material and a carbonaceous additive, such as a binder material. The conductive substrate (50) 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 (50) has surprisingly improved resistance properties in relation a substrate of the same formulation that is not carbonized. The carbonized substrate (50) can include an aerosol precursor material. The formed resistive heating element can be included in an electronic smoking article (10) to simultaneously provide resistive heating and aerosol formation with a single, unitary component.

摘要： Apparatuses, systems, and methods employing ultrasonic bonding to form filter elements for smoking articles are provided. Ultrasonic bonding can be employed to bond the fibers of filter material defining bloomed tow. Use of a plasticizer may not be necessary. Further, filter materials such as polylactic acid, which may not be bonded via a plasticizer, may be employed. However, triacetin or other additional components may be employed to provide the filter element with a desirable sensory attribute in some embodiments. Ultrasonic bonding may be conducted by an ultrasonic bonder that includes an anvil defining a pattern thereon that is selected to define a desired degree of bonding, and thereby a resulting desired firmness and/or pressure drop associated with the filter element.
