Carbon Aerogels: a study with different models of the effect resorcinol/catalyst at different ratios after pyrolysis and the effect on textural properties
Rafael A. Fonseca-Correa,Marlon Bastidas-Barranco,Liliana Giraldo,Juan Carlos Moreno-Piraján +3 more
TL;DR: In this paper, eight carbon aerogels were prepared at various resorcinol/catalytic (R/C) ratios (ranging from 25 to 1500) and followed the changes in structure after pyrolysis isotherms of N 2 to 77 K were determined to calculate the textural parameters using Dubinin-Astakhov (DA), Barret Joyner and Halenda (BJH), Non-Local Density Functional Theory (NLDFT), Quenched Solid Density functional Theory (QSDFT) models

Organic aerogels from the polycondensation of resorcinol with formaldehyde
TL;DR: In this paper, the polycondensation of resorcinol with formaldehyde under alkaline conditions results in the formation of surface functionalized polymer "clusters" which are processed under supercritical conditions to obtain low density, organic aerogels.
