| Abstract: | In this work, modification of coatings based on FP-5182 lacquer that is prepared from the copolymer of trifluorochloroethylene and vinylidenefluoride (F-32L) has been performed in order to improve their hydrophobicity. Several approaches to modification have been suggested, among which is the use of telomeric solutions of tetrafluoroethylene that were synthesized in various solvents, variation of the roughness of the coating surface by the aerosil powder, and a combination of these two approaches. The wetting properties of coatings have been studied, and improvement of the hydrophobic characteristics during their modification has been demonstrated. |
