Surface functinalized cellulose nanocrystals for cycloaliphatic epoxy (CE) resin |
| 초록 |
Unlike the aromatic epoxy resins, the cycloaliphatic epoxy (CE) resins do not have strong UV chromophore groups. Thus, they are highly resistant to ultraviolet light and more durable for outdoor applications. Recently, advances in high modulus nanofillers have shown promise in producing materials that exceed the thermal and physical properties of the neat thermoset matrix. Cellulose nanocrystals (CNCs) represent a nanofiller that is sustainable, biodegradable, and has excellent strength-to-weight ratio, and can be used as reinforcement for epoxy composites. The tranparency and absence of aromatic rings makes CNCs the ideal fillers for CEs. The introduction of surface amine functionality to the CNCs also allowed for an additional reaction with epoxy gourps. The results demonstrate that amine functionalized CNCs provide excellent dispersion in epoxy monomer and the thermomechanical properties of cured epoxy nanocomposites with amine functionalized CNCs were significantly improved. |
