Verónica Mucci, Norma E. Marcovich and Mirta I. Aranguren, "Rheological behavior of nanocellulose suspensions and nanocellulose reinforced composites" in " Elastomeric Nanocellulose Composites ", Chapter 15, Woodhead Publishing Series in Composites Science and Engineering; Pages 349-364, Accepted 2023. ISBN: 978-0-443-18608-0Concluding remarksThe content of this chapter was focused on the rheological studies of NC suspensionsand NC-reinforced elastomeric nanocomposites.The effect of NC as rheological modifiers and reinforcing NPs in composites isindubitable. However, much more work is still needed to ensure the supply NC withconstant and reliable characteristics (size, size distribution, surface charges), whichmust be paired with repeatable processing conditions to obtain similar levels of dispersionin the final products, since it is also a determining factor affecting the materialproperties. In this regard, the incorporation and adequate dispersion of the NC inpolymers in general and in rubbers in particular, still requires much research. Surfacemodifications or incorporation of interfacial agents should be considered to facilitatedispersion and allow obtaining the maximum benefit from the addition of these NPswith excellent properties.Without a doubt, and it should have been demonstrated from this review chapter,much work must still be done to contribute to the knowledge of the rheological behaviorof these nanocomposites in which so many factors need to be considered. Therehave been published more studies on the rheology of NC suspensions in low molecularweight fluids (particularly in water) due to the interest in the liquid crystal behaviorof CNC suspensions and cellulose-derived polymers. However, very little workcan be found on the rheological characterization of NC rubbery composites. Transienttests and particularly elongational tests (intrinsically more difficult to perform in fluids)contribute to understanding the behavior of the material. In general, linear andnonlinear tests should be performed on these nanocomposites to better benefit fromthe complex responses of these materials. Information provided by the agent in SIGEVAKey Words
