Morphological and Thermal Properties of Cellulose Nanofibrils Reinforced Epoxy Nanocomposites

Epoxy resins have gained attention as important adhesives because they are structurally stable, inert to most chemicals, and highly resistant to oxidation. Different particles can be added to adhesives to improve their properties. In this study, cellulose nanofibrils (CNFs), which have superior mech...
