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 transient plane source (TPS) method was used to measure the thermal characteristics of the organic aerogels. Results showed that these novelty aerogels are ecologically friendly because they are low cost and renewable but have attractive thermal properties....
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 amounts. Three different experimental procedures were used to prepare foams with different physical and thermal properties. Physical properties of the foams studied include density, as well as pore volume, pore size and cell diameter. The transient plane source (TPS) technique ...
