Abstract
Method for the preparation of a non-woven mat or paper made of carbon fibers, the method comprising carbonizing a non-woven mat or paper preform (precursor) comprised of a plurality of bonded sulfonated polyolefin fibers to produce said non-woven mat or paper made of carbon fibers. The preforms and resulting non-woven mat or paper made of carbon fiber, as well as articles and devices containing them, and methods for their use, are also described.
Claims16
A precursor of a non-woven mat or paper of carbon fiber, the precursor comprising a plurality of sulfonated polyolefin fibers bonded to each other by hydrogen bonding or ionic bonding between sulfonic acid groups on surfaces of said sulfonated polyolefin fibers, in the absence of physically-induced bonding resulting from use of heat or pressure to bond the sulfonated polyolefin fibers, wherein said polyolefin is a thermoplastic elastomeric polyolefin that is optionally partly crystalline.
