Abstract

Modifying cellulose hydrate using chemical and physicochemical techniques is one option to get rid of its drawbacks. Radiation-chemical grafting of different monomers is one of the most promising modification techniques for improving the characteristics of hydrated cellulose and its derivatives. Radiation grafting of various monomers to hydrated cellulose (H/c) and its derivatives has been the subject of numerous studies, and some of these are now starting to find widespread application in the economy. Given the aforementioned, grafting fluorine-containing monomers onto hydrated cellulose and its derivatives — whose polymers and copolymers have highly valuable and specific properties like chemical resistance, high thermal stability, decay resistance, and hydrophobicity — represents a significant scientific and practical interest. This work aims to synthesise grafted copolymers of hydrated cellulose with vinylidene fluoride from the vapour phase using a radiation-chemical method. The effects of radiation dose intensity, exposure duration, and solvent type on the process and grafted copolymer yield are investigated. Important physicochemical and functional characteristics of the original, irradiated and grafted copolymers are also examined in this study. These characteristics include sorption capacity, density, hydrophobicity, degree of whiteness, mechanical properties, thermal stability, and the type of supramolecular structure alterations brought about by grafting fluorine-containing polymers.
