Abstract
The most effective classes of polymer water repellents include acrylic polymer with perfluoroalkyl additives. However, due to the prohibition of substances with a long perfluoroalkyl linear chain longer than 6 carbon atoms by the Stockholm Convention on Persistent Organic Pollutants, there is a significant necessity to replace them with approved analogues. This work considered substituted acrylates based on commercially available hexafluoropropylene trimer and their polymerization in a supercritical CO2 medium as the most convenient way and the hydrophobizing ability on various types of surfaces. The contact angles of the coatings obtained based on these oligomers are up to 111 ° on glass and aluminum, and 130 ° on cotton fabric, which is comparable to analogs with linear perfluoroalkyl substituents.
期刊介绍：
The Journal of Fluorine Chemistry contains reviews, original papers and short communications. The journal covers all aspects of pure and applied research on the chemistry as well as on the applications of fluorine, and of compounds or materials where fluorine exercises significant effects. This can include all chemistry research areas (inorganic, organic, organometallic, macromolecular and physical chemistry) but also includes papers on biological/biochemical related aspects of Fluorine chemistry as well as medicinal, agrochemical and pharmacological research. The Journal of Fluorine Chemistry also publishes environmental and industrial papers dealing with aspects of Fluorine chemistry on energy and material sciences. Preparative and physico-chemical investigations as well as theoretical, structural and mechanistic aspects are covered. The Journal, however, does not accept work of purely routine nature.
For reviews and special issues on particular topics of fluorine chemistry or from selected symposia, please contact the Regional Editors for further details.
