Abstract
The use of both cellulose and polyurethane rubbers of the PU-8TB and PU-8A grades is discussed in the work to create film materials for draining oils. By the method of IR spectroscopy, the chemical interaction between the hydroxyl groups of cellulose and the carboxyl groups of polyurethane rubber is confirmed. Peculiarities of the thermal properties of the films are studied, which make it possible to speak of the repeated regeneration of materials from absorbed moisture without their destruction. The synthesized film materials have increased elasticity, hydrophilicity, and oleophobicity in comparison with the original cellulose film, which allows them to be used as sorbents and membranes in the field of oil and gas production. The research results showed that polyurethane rubbers PU-8TB and PU-8A, when combined with cellulose, act as functional additives in the manufacture of films capable of removing water from oils.
