제목 Eco-friendly Cellulose nanofibril-Polypropylene Nano-composites
초록 Polypropylene (PP) is one of the most popular thermoplastic polymers used in industry including automotive company. To improve physical properties, PP is often used in combination with fillers such as a glass or carbon fiber. Because eco-friendliness issues such as reducing weight, recyclability, and biodegradability have been attracting attention, cellulose nanofibril (CNF) having excellent tensile strength similar to Kevlar(~ 3.6 GPa) is emerging as a filler instead of glass or carbon fiber. Still, few obstacles should be overcome for using it as a filler such as dispersing in hydrophobic PP and oxidizing in the melt mixing process. In this study, CNF was surface-modified with inorganic nanoparticles exhibiting good dispersion in PP and thermal stability where the amount of the particles was tried to be minimized for reducing weight. The mechanical properties of the composite were analyzed according to ASTM standards. The rheological propertiy was measured using a rotatable rheometer
