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.
