Surface-modified cellulose nanocrystals

EFFECTS OF SURFACE-MODIFIED CELLULOSE NANOCRYSTALS ON STRUCTURE AND MECHANICAL PROPERTIES OF NANOCOMPOSITES... [Pg.282]

Fourier-transform infrared spectroscopy (FT-IR) is the most commonly used technique for evaluation of the chemistry of surface-modified cellulose microfibrils and nanocrystals (whiskers) [25,51,52,57-60]. However, FT-IRanalysis is not confined to the surface of the material, and is therefore best suited for qualitative evaluations of the chemistry of microfibrillar cellulose. [Pg.141]

Fortxmati et al. [56] studied PLA/nanocellulose nanocomposite films prepared by twin-screw extrusion followed by a film formation process. Cellulose nanocrystals were synthesized from cellulose microcrystals by sulphuric acid hydrolysis. The crystal surface was modified with surfactant (acid phosphate ester of ethoxylated nonylphenol) as a means to improve the dispersion of filler in PLA matrix. The presence of surfactant... [Pg.246]

Study of the incorporation of cellulose nanocrystals in a polyurethane elastomer shows the modification produced in the properties of the resulting material [154]. In this context, the surface hydroxyl groups on cellulose are reacted to produce modified cellulose crystals. The study reveals a strong dependence of materials properties on the cellulose content, a peculiar behavior appearing below the percolation threshold. [Pg.383]
