Carbon gels appear to be within the most suitable materials in different fields
such as energy storage devices, adsorbents for gas separation and catalyst
supports due to their unique combination of adequate properties in terms of
morphology, texture and composition that can be tuned during the synthesis
process, however, the conductivity of carbon gels is still rather limited [1,2]. To
overcome this limitation, the development of 3D architectures with a graphenelike
structure appears an interesting strategy to combine the porosity of carbon
gels with high electrical conductivity of the additive carbons, such as carbon
black, graphite and graphene oxide.
The objective of this work was the synthesis of carbon materials with exceptional
characteristics respect to nanoporosity development and high electrical
conductivity that allows designing suitable materials for their use in different
applications. The materials were obtained by a simple modification of the solgel
polymerization reaction of the precursors (resorcinol and formaldehyde) [3]
in presence of carbon conductive additive. These additives were incorporated
during the synthesis process which allows their cross-linking during the gelation
process. The effect of the nature of the additive, the incorporated amount and
the reaction medium (aqueous or alcoholic) were analysed in terms of porosity
and chemical composition of the final materials. The results showed multimodal
interconnected pore systems, besides an enhanced electrical conductivity
provided by the carbon additive.
