Patent number: 5651922Abstract: A polymeric composition having improved toughness and conductivity comprising carbon fibrils, at least a portion of which are in the form of aggregates, wherein, as measured on an area basis, substantially all of the aggregates are less than about 35 .mu.m in diameter. A polymeric composition having improved toughness and conductivity is prepared by combining carbon fibrils, at least a portion of which are in the form of aggregates, with a polymeric material, mixing the combination to distribute the fibrils in the polymeric material and applying shear to the combination to break down the aggregates until substantially all of the aggregates are less than about 35 .mu.m in diameter.Type: GrantFiled: June 7, 1995Date of Patent: July 29, 1997Assignee: Hyperion Catalysis InternationalInventors: Paul R. Nahass, Stephen O. Friend, Robert W. Hausslein
