PRE-EXPERIMENTAL DRAFT — EXPERIMENTAL DATA PENDING Epoxy thermosets are foundational materials in structural and functional composites but remain constrained by fossil feedstocks, permanent crosslinking, and limited end-of-life options. Here, we present a PROPOSED complete experimental study of Hempoxy vitrimers, a family of predominantly hemp-derived epoxy bionanocomposites integrating epoxidized hempseed oil (EHO), hemp lignin, hemp cellulose derivatives, and hemp-derived carbon nanomaterials. Fifteen distinct Hempoxy variants TO BE synthesized and evaluated, spanning foundational bio-epoxies, advanced vitrimer nanocomposites, and function-specific prototypes. Dynamic covalent networks based on ω -hydroxy ester transesterification, imine exchange, and disulfide metathesis enabled thermal reprocessing, chemical recycling, and self-healing while retaining thermoset integrity. Hemp-derived carbon reinforcements—including biochar, carbon nanofibers (CNF), carbon nanosheets (CNS), and graphene quantum dots (GQD)—provided tunable mechanical, electrical, and thermal functionality. Across the platform, glass transition temperatures (T g ) of 45–110 → C, topology freezing temperatures (T v ) of 65–180 → C, tensile strengths of 20–110 MPa, electrical conductivities up to 30 S m ↑1 , and retention of → 85% mechanical performance after four reprocessing cycles TARGET VALUES — EXPERIMENTAL VALIDATION REQUIRED. Closed-loop chemical recycling via aminolysis enabled recovery of both matrix oligomers and carbon fillers. These results establish Hempoxy vitrimers as a scalable, circular, and multifunctional epoxy materials platform derived primarily from Cannabis sativa biomass.
