“…The composite with 1 wt% NFC has a Young's modulus value higher than that of composite with 1 wt% B400. NFC is reported by some authors [39][40][41][42] as having a high stiffness. Cellulose and sodium alginate act as biopolymers that influence the mechanical properties of cellulose/gypsum composites.…”

We synthesized cellulose/gypsum composites in the presence and absence of sodium alginate and investigated the interaction between the composite components as well as the mechanical properties of the final composites. Four different types of cellulose fiber materials were used: cellulose UFC100, cellulose B400, nanofibrillated cellulose, and Lyocell fiber. For all investigated composites the total amount of admixed cellulose was between 1 and 2 wt%, the amount of admixed sodium alginate was 0.5 wt%. We determined the morphology of the composites and observed that the particle and fiber dimensions of the admixed cellulose affect the mode of gypsum-gypsum interlocking and the total porosity of the composites. This in turn had a substantial influence on the mechanical properties of the final composite materials. The addition of sodium alginate resulted in an increase of ultimate strain values. Composites with Lyocell fiber, a synthetic fiber, also had a high Young's modulus.

“…As discussed above, it is important to improve the mechanical properties of HPC-based materials for use in the biomedical field and for other applications (Eyholzer et al 2010;Fernandes et al 2013). Moreover, HPC has a lower critical solution temperature (LCST, *41°C) in water.…”

Cellulosic nanocomposite membranes were prepared by incorporation of cellulose nanocrystals (CNCs) into a hydroxypropyl cellulose (HPC) matrix using a mixing/evaporation technique. CNCs were obtained from filter paper using the sulfuric acid hydrolysis method with the aid of ultrasonication. The relationship between the microstructure and mechanical properties of the CNCs/HPC nanocomposite membranes was studied. Scanning electron microscopy showed that the CNCs were well dispersed in the HPC matrix, and the fracture surface demonstrated a fibrous characteristic. With increasing CNCs content, the tensile strength and Young's modulus of the CNCs/HPC nanocomposite membranes gradually increased. At 5 wt% content of CNCs, the strength was increased by 525 % and the Young's modulus by 124 % compared with pure HPC membrane. Moreover, the effect of the phase change of HPC on the mechanical properties of the CNCs 5wt% /HPC nanocomposite membranes and the corresponding mechanism were also studied.

“…Therefore, we envisaged to reinforce HPC using unmodified and carboxymethylated MFC, and we studied the impact of drying these nanofibers on their reinforcing potentials in HPC composites. (Eyholzer, et al, 2010b) The carboxymethylated nanofibers being not susceptible to hornification problems, the preservation of their ability to reinforce matrices in powder form would be highly beneficial from a practical and industrial point of view. The polymer matrix was reinforced with either never-dried (aq) or dried and redispersed (s) nanofibers.…”

In line with recent environmental policies, increased attention has been paid to the development of bio-based nanocomposite materials for several industrial applications, such as automotive, construction, packaging or medical applications. Thus, much effort has been devoted to the use of natural fibers in composite materials as an alternative to conventional inorganic fillers, traditionally used to reinforce thermoplastic matrices (i.e., glass fibers, aramid or carbon fibers, for instance).
