Improved delivery of additive materials to cigarettes is provided through the use of one or more capsules containing additive materials, such as flavor components, in the filter section of a cigarette. The sealed capsule or capsules are subjected to an external force, such as squeezing, by a smoker prior to or during smoking of the cigarette in order to release at least a portion of the additive material from the one or more capsules and expose the additive material to mainstream smoke passing through the filter. The sealed capsules provide a barrier between the additive materials and other cigarettes components, such as sorbents or filter materials, in order to reduce additive material migration into the other cigarette components prior to desired use.

A method of producing a multi-modal pore distribution activated carbon is provided herein by preparing a solution comprising a polymer precursor, mixing an additional material with the polymer precursor in the solution, cross-linking the polymer precursor with the additional material mixed therein, carbonizing the mixture of the polymer precursor and the additional material, and activating the carbonized mixture to form a multi-modal pore distribution activated carbon. The multi-modal pore distribution activated carbon can include pores less than 20 &#x212b; and greater than 30 &#x212b; or 500 &#x212b; depending upon the sorption properties desired, wherein the pore distribution of the activated carbon can be tailored to provide predetermined kinetics and/or gaseous constituent equilibrium isotherms.

Carbon beads with multimodal pore size distribution

Electroprocessed phenolic nanofibers, microfibers, beads, and films and materials including these electroprocessed materials are prepared using a delivery means (), a grounded collecting means () and a power supply () for generating an electric field.

Formation of nano-or micro-scale phenolic fibers via electrospinning

Fibrous structures composed of electrostatically prepared polysaccharide micro- and nanofibers are described which contain active agents such as drugs and/or flavorants encapsulated within the structures. When exposed to moisture, the structures are disrupted and the active agent rapidly released. The fibrous structures containing active agents such as flavorants can be incorporated into smoking articles which, when smoked, release the flavorants.
