Abstract
The disclosure relates to a method of making carbon fiber, the method comprising pyrolyzing poly(p-phenylene) (PPP) fiber at a temperature sufficient to convert PPP fiber substantially to carbon fiber. The disclosure also relates to pre-PPP polymer, methods for making PPP fiber from pre-PPP polymer and, in turn, making carbon fiber from PPP fiber.
Claims17
A method of making carbon fiber, the method comprising:
- aromatizing a pre-poly(p-phenylene) (PPP) polymer at a temperature of at least 400° C. to form poly(p-phenylene) (PPP);
- and
- pyrolyzing the PPP at a temperature sufficient to convert the PPP substantially to carbon fiber.
A method of making carbon fiber, the method comprising:
- synthesizing a pre-poly(p-phenylene) (PPP) polymer from benzene;
- aromatizing the pre-PPP polymer at a temperature of at least 400° C. to form a PPP polymer;
- and
- pyrolyzing the PPP at a temperature sufficient to convert the PPP substantially to carbon fiber.
