Four Hemp Carbon Morphologies for Vitrimer Bioepoxy Reinforcement

This research dossier profiles and compares four hemp-derived reinforcement morphologies (carbon nanosheets, biochar, short carbon fiber, and cellulose nanocrystals) for a transesterification-vitrimer bioepoxy network. It explores the thesis that because these morphologies (specifically cellulose nanocrystals, biochar, and oxidised carbon) carry surface -OH or -COOH groups, they can act as network-active components that feed and accelerate the dynamic bond exchange rather than serving as merely inert reinforcements.
