Abstract: Cellulose nanocrystals with an acicular structure ranged from 100 to 200 nm in length and 15 nm in width were extracted from Phormium tenax leaf fibres by acid hydrolysis. A two-step procedure for the extraction of nano-sized cellulose was studied and the obtained nanocrystals were characterized using morphological investigations (optical, scanning electron and atomic force microscopy), as well as physico-chemical characterization by Wide Angle X-ray Scattering, infrared spectroscopy and thermogravimetric analysis. A study of birefringence properties was also performed. The first chemical treatment leads to the production of holocellulose by the gradual removal of lignin, while the subsequent sulphuric acid hydrolysis process allows obtaining cellulose nanocrystals in an aqueous suspension. The results reported support the repeatability and the effectiveness of the procedure performed. Moreover, the high cellulose content of P. tenax fibre and their declining market interest, suggest the interest of this investigation and the possibility to use natural fibres for the production of a reinforcement phase to involve in the nanocomposite approach for industrial applications.

Effect of reaction conditions on the properties and behavior of wood cellulose nanocrystal suspensions.
TL;DR: Increased acid-to-pulp ratio reduced the dimensions of the nanocrystals thus produced and the critical concentration was increased and the biphasic range became narrower; a suspension made from a bleached kraft eucalyptus pulp gave very similar properties to the softwood nanocrystal suspension when prepared under similar hydrolysis conditions.

Optimization of the isolation of nanocrystals from microcrystalline cellulose by acid hydrolysis
TL;DR: In this article, a rapid, high-yield process was proposed to obtain an aqueous stable colloid suspension of cellulose nanocrystals/whiskers. But the results of the process were limited by the concentration of MCC and sulfuric acid, the hydrolysis time and temperature, and ultrasonic treatment time.
