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 was analyzed using a transient plane source method. Thermal conductivity of carbon meringues was found ...
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 ...
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 then cured in an oven at 85oC for 24 hours. The resultant solid foams were found ...
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 thermal analyzer measured the thermal conductivity of two TLF samples using the transient plane source (...
Lignin and phenol are inexpensive naturally derived resources that can be used to produce cost-effective organic gels. This paper aimed to examine the thermal properties of insulative organic aerogels and cryogels made from lignin and phenol. A thermal analyzer (TPS) measured the thermal conductivity of ...
