Beschreibung
Zusammenfassung:	Electrically conductive polymeric materials, having microwave susceptive characteristics, are produced by suspending a fibrous based material and a monomer precursor of a conductive polymer in an aqueous solution. Addition of a chemical oxidant induces polymerization of the monomer resulting in coating of the fibrous based material. The invention provides a susceptor material useful for cooking food items in a microwave oven, and enhances the browning and/or crispening of the items. Conductive polymer coated fibrous based materials can be formed into a paper product by conventional papermaking techniques or molded into an integral structures having microwave interactive properties.
