The applicability of epoxy resins is well explored both in academic and industrial research. Material researchers already proved the impact of curing agents on the properties of various bio-based polymer systems. Particularly in the present work, we intend to explore the significance of various curing agents in tuning the properties of bioepoxy matrix. Similar studies have a high impact on developing sustainable and environment-friendly materials with improved properties for multidisciplinary utilities. In this study, our research group targeted to improve the competence of bio-based epoxy resins for diverse applications by investigating the effect of multiple curing agents including DETDA, Citric Acid (CA), and Tannic Acid (CA), on their characteristics. Our result indicates that Citric acid and Tannic acid cured bioepoxy composite have demonstrated superior mechanical and thermal potentials, compared to the traditional DETDA-cured polymer matrix. Our findings might be useful to encourage the research and use of bio-based epoxies and similar biobased polymer systems in various industries.
