The increased relevance and prospects of studying epoxy polymer composites with the inclusion of cellulose particles of different dimensions are associated with the ability to improve their physicochemical characteristics.

We investigated the physical properties, in particular mechanical features of epoxy polymer composites doped with nanocellulose. The morphological structure of epoxy polymer composites, studied using scanning electron microscopy, shows that nanocellose particles are distributed in the nanocopposite aggregatively and uniformly, forming aggregates of 10-50 microns, and sometimes 50-100 microns, fig.1. With the swelling method, it was found that nanocellulose gives the epoxy polymer composite high resistance in an aggressive environment. It is also shown that the introduction of cellulose derivatives leads to increase the fire resistance of nanocomposites about 2 times.
