Cover Story: Sustainable biocomposites were produced combining a wood-based epoxy monomer, the resorcinol diglycidyl ether, with hydrothermal carbon prepared in mild conditions from forestry waste, the spruce bark powder. Interestingly, the DSC and in situ FT-IR investigations revealed that HTC acts as a coreactive in epoxy polymerization, catalyzing the process. The compatibility of the two components is excellent, the SEM analyses showing a good penetration of the monomer inside the HTC cells, and excellent interfacial adhesion between matrix and filler. The overall performances of these new biocomposites are excellent, with high glass transitions, hardness, and thermal stability. View this paper.
