Preparation and characterization of nanocellulose thin film from brown seaweed (sargassum sp.) reinforced x-carbon nanotube/polyvynil alcohol composites

Nowadays, celluloses not only can regenerate from nature but also by synthesizing with aid of the recent technology advancement. In this study, nanocellulose was extracted from brown seaweed Sargassum sp. via organosolvent and sulphuric acid treatments at specific ratio. It was found, the nanocellul...
