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 to be slightly higher than that of tannin-based CVC foams of low density. Carbon meringues maintained higher mechanical strength in the same range of density....
