Enhancement in Adhesive and Thermal Properties of Bio‐based Epoxy Resin by Using Eugenol Grafted Cellulose Nanocrystals

Bio-based epoxy resins are being used due to their green chemistry. They have better properties than petroleum-based resins. Recently, environment friendly nanomaterials been for different industrial applications. Cellulose nanocrystals (CNCs) among the best naturally occurring materials. Therefore, surface of cellulose modified by eugenol-based silane coupling agent (EBSCA). Chemical composition and morphologies CNCs were analyzed characterized FTIR, AFM, SEM, TEM 1H-NMR. The SEM AFM results confirmed was successfully grafted on nanocrystals. Modified demonstrated an excellent tensile strength (2190 MPa) modulus (16.00 MPa), as well storage (1622 exhibited 1wt% composites. Additionally, displayed hydrophobic behavior (CA = 102 ± 2°). corresponding significant applications in combination high stiffness This study lays a foundation towards full bio-based, polymers fabrication consumptions most desirable adhesive mechanical fields.
