摘要：Nanocellulose whiskers grafted with a polyolefin elastomer (POE-NCW) were prepared through the reaction of nanocellulose whiskers and a polyolefin elastomer (POE). This was followed by the blending of POE-NCW with polypropylene (PP), and thus, ternary nanocomposites were obtained. When the dosage of POE-NCW was 2%, the tensile strength, storage modulus, and Vicat softening temperature of the ternary nanocomposites increased by 60%, 35%, and 13 degrees C, respectively. A core-shell-like cladding structure was formed by the coating of POE on the nanorigid particles; the toughness and rigidity of the composites were both significantly improved, and this prevented brittle fracture under impact and enlarges the range of applications for PP composites.
