- Аннотация: Amphiphilic diblock copolymers (DC) of 2,3,4,5,6-pentafluorostyrene (PFS) and 2-hydroxyethyl methacrylate (HEMA) of different composition and molecular weights were prepared by two-step reversible addition–fragmentation chain transfer (RAFT) polymerization and first used for preparation of superhydrophobic coatings for cotton/polyester fabrics. The transition from hydrophobic to superhydrophobic coatings is controlled by the ratio between poly(2,3,4,5,6-pentafluorostyrene) (PPFS) block and poly(2-hydroxyethyl methacrylate) (PHEMA) block lengths (PnPFS/PnHEMA). The increase in PnPFS/PnHEMA is accompanied by a significant increase in water (θН2О) and diiodomethane (θCH2I2) contact angles, which reach the plateau at PnPFS/PnHEMA = 3.5 and remains almost constant up to PnPFS/PnHEMA = 6.2. Surface modification of the cotton/polyester fabric with the DC having PnPFS/PnHEMA = 6.2 produced superhydrophobic surface with θН2О = 158 4 º and contact angle hysteresis CAH = 5 ± 2 °, and θCH2I2 = 107 3 º.
