The pore structures of carbon aerogels were designed and controlled by changing conditions for both the microemulsion-templated sol–gel polymerization and the KOH activation processes. The resulting pore structures were characterized by means of N 2 adsorption and SEM. A new pore model is proposed and the relationship between the pore structures of the activated carbon aerogels (ACAs) and...
We have developed a method that would allow for the fabrication of carbon aerogel (CA) spheres. The inverse phase suspension polymerization of resorcinol and formaldehyde monomers with Na 2 CO 3 as a catalyst followed by supercritical drying was explored. The effects of the chemical formulation and processing procedures and the conditions of the structures of organic and related carbon...
Carbon aerogels were successfully fabricated by a microemulsion-templated sol–gel polymerization method. When a suitable molar ratio of surfactant to resorcinol (S/R) and an appropriate resorcinol–formaldehyde concentration were selected, the organic gels thus obtained could be dried with little shrinkage by heating at ambient pressure. The size of carbon nano-particles and the pore size of carbon...
