This proposal presents a novel dual-batch modied lignin architecture for creating 100% bio-based vitrimer epoxy matrices derived from hempseed oil. The Seshat Lignin system combines maleinated lignin (carboxyl/aldehyde functionalities) and Mannich lignin (amine functionalities) with epoxidized hempseed oil to establish a self-catalyzing, dual-dynamic covalent network. This architecture enables both transesterication and imine exchange mechanisms without external catalysts. A key innovation is the compatibility with a graded reinforcement spectrum spanning from native hemp bast fiber to carbonized morphologies (biochar, activated carbon, carbonized hemp fiber, hemp graphene/nanosheets), all derived from hemp feedstock. The dual-lignin chemistry provides adaptive interface compatibility across hydrophilic to graphitic surfaces. Additionally, an advanced formulation pathway incorporating furfuryl glycidyl ether (FGE) as a reactive diluent and dynamic bond modulator is proposed to enhance processability and introduce thermoreversible Diels-Alder chemistry. This pre-experimental document outlines the theoretical framework, hypothesized reaction mechanisms, detailed protocols for laboratory validation, and expected outcomes for materials scientists and polymer chemists. #Hempoxies
