This article describes a thorough investigation of the physical and thermal properties of lignin based polyurethane building materials. The materials were created with lignin polyol and isocyanate. Factors investigated included compressive strength, thermal conductivity, burning behaviour, and morphology. The authors determined that compressive strength depended ...
The properties of carbonized lignin nanoparticles were investigated to determine if this material could be used as an environmentally-friendly alternative to carbon black. The observed surface area of the carbonized lignin was found to be higher than that of carbon black because the powder is ...
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 (...
