The qualitative properties of cellulose-containing consumer goods are determined by the characteristics of cellulose, which depend on the type of plant materials and methods for its extraction. Cellulose materials composed of the nanoscale fibrils, so called nanocellulose (NC), draw great attention as they are lightweight, electrically conductive, nontoxic, and optically transparent in the crystalline form [1]. 
The preparation of pulp and nanocellulose from non-wood plant materials, as well as improved properties of paper and cardboard was described in details recently [2]. For the development of new materials based on NC, knowledge of the mechanisms of bonding NC to the surface of various materials is of great importance. For this, we studied NC samples both in liquid form and in the form of solid films that were deposited on glass, quartz, and silicon substrates. The interaction between NC fibrils was modified by the inclusion of some additives, such as oxide micro / nanoparticles, graphene oxide, and carbon nanotubes. The non-destructive methods: XRD, AFM, TEM, FTIR, viscosymetry, densitomety, scanning force and electron microscopy as well as optical microscopy, were used to characterize morphology and structure of prepared nanocellulose and its composites. Effect of temperature on characteristics of the NC and NC composites was studied and analyzed.
