Carbon meringues derived from flavonoid tannins

Author(s): , , , ,

Method:

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): , , , , , ,

Method:

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 ...

New tannin-lignin aerogels

Author(s): , , , , , ,

Method:

Tannin and lignin are organic materials that are more cost-effective than synthetic, non-renewable phenolic compounds. In this paper, tannin-lignin-formaldehyde (TLF) composites were used to synthesize thermally insulative mesoporous aerogels. A ...

Biomass-derived, thermally conducting, carbon foams for seasonal thermal storage

Author(s): , , ,

Method:

Seasonal thermal storage based on phase change materials (PCMs) require a thermally conductive host because they typically have low thermal conductivities. In this study, tannin-based composite carbon foams were prepared ...

Modification of tannin based rigid foams using oligomers of a hyperbranched poly(amine-ester) 

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

Method:

This paper examined the synthesis of hyperbranched polymers (HBPs) and how their hydroxyl end groups help form networks in tannin-based foams. A Hot disk TPS 2500 measured the thermal conductivity of ...

Highly mesoporous organic aerogels derived from soy and tannin 

Author(s): , , , , , ,

Method:

The first soy and tannin based organic aerogels with 91% naturality have been developed by researchers, and they have low bulk density but high volumes of mesopores. In this experiment, the ...

Tailoring the structure of cellular vitreous carbon foams

Author(s): , , , , ,

Method:

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 ...
