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]
