For this, a series of materials were prepared by the polycondensation of resorcinol\/formaldehyde mixtures in the presence of increasing amounts of carbon black. The conductivity of the carbon gel\/CB composites increased considerably with the amount of CB, indicating a good dispersion of the additive within the carbon matrix. A percolation threshold of ca. 8 wt.% of conductive additive was found to achieve an adequate \u201cpoint to point\u201d conductive network. This value is higher than that reported for other additives, owing to the synthetic route chosen, as the additive was incorporated in the reactant\u2019s mixture (pre-synthesis) rather than in the formulation of the electrodes ink (post-synthesis). The CB strongly influenced the development of the porous architecture of the gels that exhibited a multimodal mesopore structure comprised of two distinct pore networks. The microporosity and the primary mesopore structure remained rather unchanged. On the contrary, a secondary network of mesopores was formed in the presence of the additive. Furthermore, the average mesopore size and the volume of the secondary network increased with the amount of CB.<\/jats:p>","DOI":"10.3390\/ma13010217","type":"journal-article","created":{"date-parts":[[2020,1,6]],"date-time":"2020-01-06T03:48:48Z","timestamp":1578282528000},"page":"217","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Carbon Black as Conductive Additive and Structural Director of Porous Carbon Gels"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6341-1910","authenticated-orcid":false,"given":"Ana","family":"Casanova","sequence":"first","affiliation":[{"name":"CEMHTI, CNRS (UPR 3079), University Orl\u00e9ans, 45071 Orl\u00e9ans, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5893-1508","authenticated-orcid":false,"given":"Alicia","family":"Gomis-Berenguer","sequence":"additional","affiliation":[{"name":"CEMHTI, CNRS (UPR 3079), University Orl\u00e9ans, 45071 Orl\u00e9ans, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aurelien","family":"Canizares","sequence":"additional","affiliation":[{"name":"CEMHTI, CNRS (UPR 3079), University Orl\u00e9ans, 45071 Orl\u00e9ans, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick","family":"Simon","sequence":"additional","affiliation":[{"name":"CEMHTI, CNRS (UPR 3079), University Orl\u00e9ans, 45071 Orl\u00e9ans, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6394-4760","authenticated-orcid":false,"given":"Dolores","family":"Calzada","sequence":"additional","affiliation":[{"name":"Laboratorio de Innovaci\u00f3n en Plasmas (LIPs), Universidad de C\u00f3rdoba, 14071 C\u00f3rdoba, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9517-8132","authenticated-orcid":false,"given":"Conchi O.","family":"Ania","sequence":"additional","affiliation":[{"name":"CEMHTI, CNRS (UPR 3079), University Orl\u00e9ans, 45071 Orl\u00e9ans, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,1,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Beguin, F., and Frackowiak, E.
