CARBON FIBERS OBTAINED FROM SILICON TREATED POLYOLEFIN PRECURSOR FIBERS

摘要

A carbonaceous fiber is prepared from a polyolefin fiber. The polyolefin fiber is stabilized and is treated with a silicon source. In one instance the silicon source is a siloxane. In one instance the polyolefin fiber is stabilized by sulfonation. In one instance the carbonaceous fiber has 90-100 weight percent Carbon, 0.1-1 weight percent Silicon, 0.1-1 weight percent Nitrogen.
