Abstract

Nanoscience is a broad field that includes nanophysics and nanochemistry. Nanotechnologies are aimed at obtaining nanoparticles with new properties and creating materials and devices based on them. This is one of the modern trends in the development of science in the 21st century.

Based on the study of information about nano-sized materials, the mechanisms of their production and changes in their properties, we will consider the technology for producing nanocellulose from organic substances, i.e. from cellulose. The article describes a technology that examines devices for producing nanocellulose and the principles of their operation, as well as a combined method of purification and acid hydrolysis with high-pressure homogenization for the production of nanocellulose on an industrial scale. The types of nanocellulose and their microscopic images are also described. Our research work is aimed at obtaining nano-sized cellulose. Cellulose is one of the most common natural polymers that is part of an important part of the tissues of annual and perennial plants, algae, bacteria and fungi. Using this raw material, it is proposed to obtain nanocellulose, since cellulose is a linear homopolysaccharide, a macromolecule consisting of monomeric anhydride-β-D-glucopyranose units linearly linked to each other by 1→4-glucosidic bonds.
