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

Author(s): , , , ,

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 oxidation resistance of micro-cellular Si–SiC foams derived from natural resins

Author(s): , , , , , ,

Si-SiC composite foams were prepared using tannin-based foams as templates. The foams were prepared by four different methods for the determination of which method would best produce a foam with ...

Tannin/furanic foams without blowing agents and formaldehyde

Author(s): , , , ,

The purpose of this study was to produce an environmentally friendly foam using tannins, that did not contain any formaldehyde or blowing agents. Two experimental tannin foams were compared to ...

Structure and properties of rigid foams derived from quebracho tannin

Author(s): , , , ,

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 ...

Thermal conductivity improvement of composite carbon foams based on tannin-based disordered carbon matrix and graphite fillers

Author(s): , , ,

Composite carbon foams were prepared by mixing tannin-based resin with various graphite powders in an effort to improve the thermal conductivity relative to pristine carbon foams in order to use ...

Emulsion-templated porous carbon monoliths derived from tannins

Author(s): , , ,

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 ...

A new method for preparing tannin-based foams

Author(s): , , , ,

The authors present a novel method for the preparation of highly porous tannin-based meringues by shear mechanical mixing of tannin, hexamine, and Kolliphore® ELP in water. The liquid foam was ...

Closed-cell carbon foams from diphenolic acid-based polybenzoxazine

Author(s): , , , , , , ,

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): , , , , ,

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 ...
