“…Gao et al also modified BC fibrils with silanes and the strength was optimum at 20 vol% fibrils [12]. More recently, Kargarzadeh et al used silane compounds to modify cellulose nanocrystals and studied UP composites with up to 6 wt% of nanocrystals [13]. Builes et al used block copolymers to disperse 1 wt% of CNF in UP resin, and observed marginal increase in fracture toughness [14].…”

Biocomposites reinforced by natural plant fibers tend to be brittle, moisture sensitive and have limited strength. Wood cellulose nanofibers (CNF) were therefore used to reinforce an unsaturated polyester matrix (UP) without the need of coupling agents or CNF surface modification. The nanostructured CNF network reinforcement strongly improves modulus and strength of UP but also ductility and toughness. A template-based prepreg processing approach of industrial potential is adopted, which combines high CNF content (up to 45vol%) with nanoscale CNF dispersion. The CNF/UP composites are subjected to moisture sorption, dynamic thermal analysis, tensile tests at different humidities, fracture toughness tests and fractography. The glass transition temperature (T g ) increases substantially with CNF content.Modulus and strength of UP increase about 3 times at 45vol% CNF whereas ductility and apparent fracture toughness are doubled. Tensile properties at high humidity are compared with other biocomposites and interpreted based on differences in molecular interactions at the interface.

“…Cellulose nanocrystal (CNC) has attracted a great deal of interest in the composites field due to its appealing intrinsic properties such as good mechanical properties (longitudinal modulus close to 150 GPa), high aspect ratio (10~70) and high surface area (Kargarzadeh, Sheltami, Ahmad, Abdullah, & Dufresne, 2015;Arrieta, Fortunati, Dominici, López, & Kenny, 2015;Klemm, et al, 2011;Habibi, Lucia, & Rojas, 2010;Moon, Martini, Nairn, Simonsen, & Youngblood, 2011), as well as the fact that it is renewable and biodegradable (Danial, et al, 2015). Beside the field of traditional polymers (Iyer, Schueneman, & Torkelson, 2015;Mariano, E. I. Kissi, & Dufresne, 2015;Bettaieb, Khiari, Dufresne, Mhenni, & Belgacem, 2015).…”

“…Silane was reported to increase the hydrophobic surface area of CNCs [45]. Kargarzadeh et al [55] used silane to surface-treat CNCs and the reinforced unsaturated polyester resin showed an improvement in strength and stiffness, and an exceptional increase in toughness by 96%. Due to the less hydrophilicity after surface treatment, the water absorption was decreased with CNCs.…”

Abstract. Cellulose nanomaterials (CNs) have been successfully applied to a variety of scientific areas in recent years with remarkable engineering utilities. As sustainable materials of huge abundance, CNs show significant potentials in fine-tune the microstructures and kinetics from the nano-level. This paper reviews recent key advancements of the use of CNs in the fields of pharmaceutical science and pharmacology. A broad overview of the development of CNs is provided, and the current methods to obtain the materials are discussed. The different types of processing techniques are reviewed, that are critical to the applications in pharmaceutical science and pharmacology. The key breakthroughs of applications in major fields are discussed, including oral administration, topical administration, tissue scaffolds, and antibacterial applications.
