CNC

，表面取代度为12.60%；CNC-

-PLA的表面接枝率为431.90 mg/g

CNC

，表面取代度为9.14%. 通过Hansen溶解度参数对复合体系的相容性进行预测，进一步采用显微红外成像对CNC在基质中的分散性进行可视化评估. 结果显示，CNC的表面修饰显著改善

了其与基质间的相容性和分散性. 复合材料的热力学性能进一步证明了体系中的界面增容和力学增强效应.

Abstract

Cellulose nanocrystals (CNC) are commonly used as reinforcing fillers for composites due to their excellent mechanical properties and other advantages

and the mechanical enhancement of composites is often closely related to the dispersion of the nanoreinforcing fillers as well as the interfacial compatibility. In this study

castor oil and polylactic acid chains were covalently grafted on the surface of CNC

respectively

to enhance its compatibility with polyester matrix and prepare mechanically enhanced composites. The surface grafting rate of CNC-

-CO was calculated to be 205.30 mg/g

CNC

with a surface substitution of 12.60%

while the surface grafting rate of CNC-

-PLA was 431.90 mg/g

CNC

with a surface substitution of 9.14%. The compatibility of the composite systems was predicted by the Hansen solubility parameters

and the dispersion of CNC in the matrix was further evaluated visually using micro-infrared imaging. The results showed that the surface modification of CNC significantly improved the compatibility and dispersion between

it and the matrix. The thermodynamic properties of the composites further demonstrated the interfacial capacitation and mechanical enhancement effects in the systems.
