发明名称 Submicron-scale graphitic fibrils, methods for producing same and compositions containing same
摘要 The present invention provides a submicron-scaled graphitic fibril having a diameter or thickness less than 1 μm, wherein the fibril is free of continuous thermal carbon overcoat, free of continuous hollow core, and free of catalyst. The fibril is obtained by splitting a micron-scaled carbon fiber or graphite fiber along the fiber axis direction. The diameter or thickness is preferably less than 500 nm and can be greater or less than 100 nm. These graphitic fibrils exhibit exceptionally high electrical conductivity, thermal conductivity, elastic modulus, and strength. The present invention also provides several products that contain submicron graphitic fibrils: (a) paper, thin-film, mat, and web products; (b) rubber or tire products; (c) energy conversion or storage devices, such as fuel cells, lithium-ion batteries, and supercapacitors; (d) adhesives, inks, coatings, paints, lubricants, and grease products; (e) heavy metal ion scavenger; (f) absorbent (e.g., to recover spill oil); (g) sensors; (h) friction and brake components; (i) radiation-shield components; and (j) nanocomposite materials.
