A series of polyhedral oligomeric silsesquioxane (POSS) based hybrid terpolymers P(POSS-MMA-(HFPO)3MA) were synthesized and characterized by NMR, FT-IR, GPC, DSC and TG. The thermal properties of these terpolymers were improved by the introduction of POSS cage. The cotton fabrics coated with these terpolymers possessed excellent water and oil repellency. The water and salad oil contact angle could be achieved from â¼140° to 152° and from â¼127° to 144° respectively as the content of POSS in the terpolymer increased from 6.4 wt% to 13.4 wt%. Compared with P(MMA-(HFPO)3MA) copolymer-coated cotton fabrics, POSS-based terpolymer coated cotton fabrics showed better oil repellency with a tendency of first increasing and then decreasing with an increase of the POSS content. The n-hexadecane (surface tension: 27.4 mN/m, 20 °C) contact angle reached â¼117° for coated cotton fabrics with terpolymer containing 9.5 wt% of POSS.
