“…However, CNFs were used in combination with SDBS to enhance their dispersion potential and as a requirement for application in printed electronics. There are also different examples in which nanocellulose materials are used as an aqueous stabilizer of 0D metallic NPs, normally acting as a template during their synthesis [ 48 , 51 , 52 , 53 ]. For instance, it has been reported that TEMPO-oxidized CNCs grafted with amino groups were able to stabilize Ag NPs in water [ 51 ].…”

“…It is important to note that the presence of polyvinylpyrrolidone was required at the ink for increasing the compatibility between Au NPs and CNCs. Moreover, CNCs have been employed for the synthesis and stabilization of zero-valent iron NPs (nZVI) in aqueous media [ 48 ]. Several proportions of CNCs/nZVI were analyzed, finding an optimal ratio at 8/1 that yields long-term colloidal stabilization, which can be potentially employed for water remediation [ 48 ].…”

Nanocellulose, a nanoscale derivative from renewable biomass sources, possesses remarkable colloidal properties in water, mechanical strength, and biocompatibility. It emerges as a promising bio-based dispersing agent for various nanomaterials in water. This mini-review explores the interaction between cellulose nanomaterials (nanocrystals or nanofibers) and water, elucidating how this may enable their potential as an eco-friendly dispersing agent. We explore the potential of nanocellulose derived from top-down processes, nanocrystals, and nanofibers for dispersing carbon nanomaterials, semiconducting oxide nanoparticles, and other nanomaterials in water. We also highlight its advantages over traditional methods by not only effectively dispersing those nanomaterials but also potentially eliminating the need for further chemical treatments or supporting stabilizers. This not only preserves the exceptional properties of nanomaterials in aqueous dispersion, but may even lead to the emergence of novel hybrid functionalities. Overall, this mini-review underscores the remarkable versatility of nanocellulose as a green dispersing agent for a variety of nanomaterials, inspiring further research to expand its potential to other nanomaterials and applications.

“…Cellulose nanocrystals (CNCs) derived from biomass have been widely reported as nano-fillers in polymer nanocomposites, [26][27][28][29][30] and the high strength and high aspect ratio of CNCs endow excellent performance to polymers. 31,32 However, the distribution of CNCs in hydrophobic polymer matrices such as PLA remains a significant problem due to the inherent hydrophilicity of CNCs, which dramatically weakens the performance of CNCs and accordingly the mechanical properties of the polymer matrices.…”

Poly(L-lactic acid) (PLLA) is a biodegradable polymer that has attracted increasing attention due to its fantastic properties. Nevertheless, the disadvantages of PLLA, such as low crystallization rate and brittleness, limit its wide commercial applications. In the present work, electrospun stereocomplex PLA fibers (Sc-fibers) and PLLA grafted cellulose nanocrystals (g-CNCs) are prepared as nano-fillers and then blended with PLLA matrix to prepare different nanocomposites. Both of nano-fillers would accelerate the crystallization rate of PLLA, and as expected, g-CNCs have much stronger nucleation ability towards PLLA than Sc-fibers. Nevertheless, the crystallization of PLLA will decrease to some extent in the presence of both nano-fillers of g-CNCs and Scfibers due to the preferential formation of stereocomplex crystals on the surfaces of CNCs. Moreover, the presence of nano-fillers would enhance the mechanical properties of PLLA, such as the elongation at break can increase by four times after incorporating both g-CNCs and Sc-fibers. This work provides a new consideration for designing different nano-fillers, especially for polymer matrices with low crystallization ability and brittleness.
