Abstract

A process to manufacture nanocrystalline cellulose from cellulose having a low hemicellulose content, said process comprising the steps of:

exposing said cellulose to a microemulsion composition for a first pre-determined period of time, thereby creating a soaked cellulose;optionally, exposing the soaked cellulose to a sonication step for a second predetermined period of time; andexposing the resulting mixture to a H2O2 with FeSO4 or CuSO4 under acidic conditions for a third pre-determined period causing hydrolysis of the cellulose;wherein the nanocrystalline cellulose will have a crystallinity index of more than 50% and an aspect ratio ranging from 10:1 length to width to 50:1 length to width.
