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 ...
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 as the plasticizer. Crosslinking was carried out using a traditional or microwave oven. Samples differed ...
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 since there were a number of active isocyanate groups on the PUR that was used, ...
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 a pore size under 200 µm. The foam samples were characterized by SEM, XRD, and Raman ...
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 two conventional foams, one containing both formaldehyde and blowing agents, and the other containing only ...
