Biobased foams from condensed tannin extracts from Norway spruce (Picea abies) bark

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

Research found tannins have been successful as monomers to produce organic foams with superior properties for thermal insulation. Norway spruce (Picea abies) tannins were extracted and used to prepare tannin/...

Carbon meringues derived from flavonoid tannins

Author(s): , , , ,

This article investigated new macro-cellular carbons, called carbon meringues, formed by whipping an aqueous solution of tannin until liquid foam is obtained. Carbon meringues were fully investigated, and thermal conductivity ...

Tannin-based monoliths from emulsion-templating

Author(s): , , , , , ,

Porous monoliths, often referred to as polymerised High Internal Phase Emulsions (polyHIPEs), are materials made of polymers that have applications ranging from chemical engineering to biomedicine. In this paper, a ...

Insulation rigid and elastic foams based on albumin

Author(s): , , , , , ,

This article discusses the creation and characterization of albumin based rigid and elastic foams. These foams were created using formaldehyde as the hardener for the protein, while camphor was used ...

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 ...

Systematic studies of tannin–formaldehyde aerogels: preparation and properties

Author(s): , , , ,

A variety of tannin-formaldehyde aerogels were produced in order to examine the effects of pH and dilution during their manufacture. The authors produced a phase diagram that could describe them. ...

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 ...
