Title:
MICROSCOPIC CARBON FIBER WITH A VARIETY OF STRUCTURES
Document Type and Number:
WIPO Patent Application WO/2005/095687
Kind Code:
A1
Abstract:
A microscopic carbon fiber formed of a fiber-like substance of such a structure that cylindrical graphen sheets are stacked on each other in a right-angled direction to the axis thereof, wherein the sheets forming a cylinder comprise a polygonal cross section perpendicular to the axis thereof, the maximum diameter of the cross section is 15 to 100 nm, an aspect ratio is 105 or less, and ID/IG measured by Raman spectroscopic analysis is 0.1 or less. By adding a small amount of carbon fiber, physical properties such as electric characteristics, mechanical properties, and thermal properties can be increased without impairing the characteristics of a matrix.
