N2 - Three tadpole-shaped POSS fluorinated acrylate polymers, POSS-poly (trifluoroethyl acrylate) (POSS-PTFEMA), POSS-poly (methyl methacrylate)-b-poly (trifluoroethyl methacrylate) (POSS-PMMA-b-PTFEMA) and POSS-poly (trifluoroethyl methacrylate)-b-poly (methyl methacrylate) (POSS-PTFEMA-b-PMMA), were synthesized via atom transfer radical polymerization (ATRP) using 3-chloropropyl-hepta (phenyl) POSS (POSS-Cl) as the initiator. The structures of the initiator and the related three hybrid polymers were characterized with fourier transform infrared (FT-IR) spectroscopy and nuclear magnetic resonance (NMR) techniques, and the molecular weights and molecular weight distributions were determined with gel permeation chromatography (GPC). Thermal stabilities of the hybrid polymers were evaluated by thermal gravimetric (TG) method, and the results indicated that the hybrid polymers exhibited excellent thermal stability. In addition, surface hydrophobic and oleophobic properties of the hybrid polymers were shown that on the polymer films the water contact angles were about 97°~101°, and the dihexyl contact angles were about 36°~40°. Furthermore, it was found that with the increasing of the degree of polymerization of TFEMA, the surface energy was decreased which leaded higher contact angles.
