Dear all,
we are trying to impregnate a porous ceramic body with furfuryl alcohol to get as much carbon as possible upon pyrolysis
Any suggestion on how to handle the procedure? I mean crosslinking agent, mixing, thermal treatment and so forth
Thanks a lot
Alberto
Interesting question, currently I am also involved in a similar topic, I would suggest treating the ceramic with some oxidizing agent/solution to introduce Surface-OH groups that may format hydrogen bond to -O- and -OH groups.
Dear Alberto Ortona

Hi Alberto Ortona
You may use the spray pyrolysis process. Spraying the alcoholic solution over the ceramic bed.

Dear Alberto Ortona that's a very interesting question. I think a more or less direct answer to your question is provided in the following potentially useful article:

Unfortunately the paper has not been posted on RG as public full text. Perhaps you can access it through your institution.
Also of interest could be the following article:

In this case all three authors have RG profiles. Thus there is a good chance that you can request the full text directly from one of the authors.
I hope this helps. I wish you good luck with your experiments!
