Fabrication of Carbon Fiber Embedded Carbon Aerogel via Supramolecular Assembly of Small Molecules in the Precursor Gel
Carbon fiber embedded carbon aerogel (CFECA) was fabricated through simple addition of small organic gelators to the precursor formed by furfural and resorcinol. The surface area of the obtained CFECA decreased compared to that from the precursor without small gelator, but the electrical conductivities of the CFECA increased obviously. The maximum conductivity of the CFECA can reach 2.55 × 105 S/m which is more than three times as that of the referenced common carbon aerogel. The formation of CFECA was characterized by SEM as well as TEM observation.
