What are Nano Cellulose Crystals?
Nano Cellulose Crystals (NCCs), also known as cellulose nanocrystals (CNCs), are crystalline nanoparticles extracted from cellulose fibers. They are characterized by their high strength, stiffness, low density, and high surface area. The unique properties of nano cellulose materials stem from their nanoscale dimensions and highly ordered crystalline structure, offering superior mechanical, optical, and barrier characteristics compared to traditional cellulose.
The nano cellulose extraction methods typically involve acid hydrolysis of various cellulosic sources like wood pulp, cotton, or agricultural waste. This process removes the amorphous regions of cellulose, leaving behind the highly crystalline segments. Continuous nano cellulose research and development is refining these techniques to improve yield, purity, and cost-effectiveness, paving the way for broader industrial adoption.
