Chemical modification of tannin/furanic rigid foams by isocyanates and polyurethanes

Author(s): Alain Celzard, Antonio Pizzi, M. C. Basso, V. Fierro, X. Li

Polymeric tannin/furanic foams fortified with polyurethane (PUR) and 4,4’ diphenylmethane diisocyanate (pMDI) were prepared. The thermo-physical and mechanical properties of the produced foams were investigated experimentally. It was found that ...

Structure and properties of rigid foams derived from quebracho tannin

Author(s): A. Martinez de Yuso, Alain Celzard, Antonio Pizzi, M.C. Lagel, V. Fierro

Rigid foams were prepared using quebracho tannins and their physical and thermal properties were determined experimentally. These properties were then compared to those of rigid foams derived from mimosa tannins ...

Emulsion-templated porous carbon monoliths derived from tannins

Author(s): A. Szczurek, Alain Celzard, Antonio Pizzi, V. Fierro

The authors have prepared highly porous, monolithic, carbon polymerised high internal phase emulsions (carboHIPEs) using tannins as the base material. This material was considered to be one of the most ...

Closed-cell carbon foams from diphenolic acid-based polybenzoxazine

Author(s): Alain Celzard, Alicia Martinez de Yuso Arisa, Alicia Martínez de Yuso Arisa, Andrzej Szczurek, Camilo Javier Zuniga Ruiz, Juan Carlos Ronda, Vanessa Fierro, Virginia Cadiz

Carbon foams were prepared from diphenolic acid-based benzoxazine foams by pyrolysis under nitrogen atmosphere. The method used in this article produced foams containing a large fraction of closed cells which ...

Tailoring the structure of cellular vitreous carbon foams

Author(s): Alain Celzard, Antonio Pizzi, F. L. Braghiroli, M. C. Basso, V. Fierro, X. Li

The authors set out to prepare cellular vitreous carbon (CVC) foams with varying thermal and physical properties. This was accomplished by using tannin-based resin modified by different isocyanates in varying ...
