Tortuosity of the porous structure of carbon gels

Extensive studies on the correlation between synthesis variables and final properties of resorcinol-formaldehyde carbon gels have been performed. This knowledge allows us to obtain with analogous mean pore sizes porosity from different combinations variables. However, although materials exhibit these similar characteristics, their behaviors may be very in certain applications. Since distribution connectivity polymeric clusters are strongly affected by such as amount water methanol precursor solution, it seems that tortuosity thus permeability also dependent factors. Further analysis a series apparent same shows how an increase or suitable combination content pH solution used for polymerization process generate less tortuous structures. attain even finer tuning porous structure RF either reduce pressure drop residence time solutes separation processes.
