Abstract
A method of forming a carbon foam precursor for use in the formation of carbon foam materials. The carbon foam precursor comprises an aerogel of polymeric material which has a coating layer thereon, the coating layer comprising a material susceptible to dielectric heating, for example carbon nanotubes. The carbon foam precursor is suitable for forming into a carbon foam material using a dielectric heating step, despite the aerogel of polymeric material not being susceptible to dielectric heating, without adversely affecting the structure and physical properties of the carbon foam so formed. A carbon foam precursor, a carbon foam material and a method of forming such a carbon material are also disclosed.
Claims18
A method of preparing a carbon foam precursor for a carbon foam formation process, the method comprising the steps of:
- a) forming an aerogel from a polymeric material;
- and
- b) forming a coating layer on the aerogel of polymeric material wherein the coating layer comprises a dielectric heating susceptor material.
A carbon foam precursor comprising an aerogel of a crosslinked polymeric material and a coating layer on the aerogel, the coating layer comprising a dielectric heating susceptor material.
