Аннотация:A chemical modification of cellulose diacetate by phthalate and sized aerogels have a predominantly spherical morphology and nitrate was performed to increase solubility in organic solvents amorphous structure. Suspensions of porous particles of nitro- and change the electrical properties. The role of substituents on and phthalylated cellulose derivatives in silicone oil have an the conductivity, permittivity, and polarizability of cellulose increased dielectric permittivity compared to cellulose diacetate films is revealed. It has been shown that highly porous micro particles. Produced particles are novel promising material with particles can be obtained from cellulose derivatives by a simple tunable electrical properties for advanced applications in and technological freeze-drying method. The resulting micro composites, including for electrorheological fluids.
