Abstract
A composite for use in smoking articles such as cigarettes is described comprising a zeolite membrane coated upon an activated carbon-containing substrate. The substrate may be a fiber, fabric, particle, granule or monolith. The composite is prepared by contacting zeolite precursors with the substrate and hydrothermally synthesizing the membrane upon the substrate. The substrate may be pretreated to provide activation sites for adhesion and growth of the membrane. By selection of the zeolite components, the composite may be tailored to selectively remove constituents of tobacco smoke while simultaneously controlling access to the substrate thereby prolonging the shelf life of the activated carbons.
