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

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 since there were a number of active isocyanate groups on the PUR that was used, ...

Structure and properties of rigid foams derived from quebracho tannin

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 and pine tannins to determine if the nature of the flavonoid affects the properties of ...

Emulsion-templated porous carbon monoliths derived from tannins

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 environmentally friendly carboHIPEs to have been prepared based on the fact that it is almost ...

Closed-cell carbon foams from diphenolic acid-based polybenzoxazine

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 is uncommon for carbon foams. The foams studied were found to possess similar mechanical properties ...

Tailoring the structure of cellular vitreous carbon foams

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 amounts. Three different experimental procedures were used to prepare foams with different physical and thermal ...
