The research on cellulose fiber-reinforced nanocomposites has increased by an unprecedented magnitude over the past few years due to its wide application range and low production cost. However, the incompatibility between cellulose and most thermoplastics has raised significant challenges in composite fabrication. This paper addresses the behavior of plasma-modified polyethylene (PE) reinforced with cellulose nanofibers extracted from isora plants (i.e., isora nanofibrils (INFs)). The crystallization kinetics of PE–INF composites were explained using the Avrami model. The effect of cellulose nanofillers on tuning the physiochemical properties of the nanocomposite was also explored in this work. The increase in mechanical properties was due to the uniform dispersion of fillers in the PE. The investigation on viscoelastic properties confirmed good filler–matrix interactions, facilitating the stress transfer.

Abstract Cellulose nanofiber is one of the promising materials for its eco-friendliness as well as high mechanical performance and high functionalities. Nanocomposites with cellulose nanofiber matrixes and inorganic nanofillers also possess more excellent mechanical properties by the reinforcement effects of the nanofillers. The mechanical reinforcement effects depend in a large part on the interfacial interaction between the nanofillers and the cellulose matrixes and the dispersion of the nanofiller in the nanocomposites. The quantitative evaluation of the reinforcement effects is insufficient, which is desired for the material design of industrial use of the cellulose composites. In this study, we used nanocomposites of cellulose nanofibers and montmorillonite with various surface properties. Their mechanical properties were investigated through tensile tests and the stress transfer to the nanofillers in nanocomposites with various combinations of cellulose nanofibers and nanofillers was analyzed through the X-ray diffraction method. The strong correlation between Young’s modulus and stress transfer coefficients was revealed. In particular, the composites of TEMPO-oxide cellulose nanofiber and ion-exchanged montmorillonite possessed not only the highest Young’s modulus but also the largest stress transfer coefficients. The large mechanical reinforcement effect of the loaded montmorillonite filler was observed and was attributed to the electrostatic interaction of the interface between the cellulose matrix and the montmorillonite filler.
