Novel fluoroalky end‐capped oligomers/titanium dioxide nanocomposites were prepared by the hydrolysis of titanium isopropoxide in the presence of fluoroalkyl end‐capped N ‐(1,1‐dimethyl‐3‐oxobutyl)acrylamide oligomer [R F ‐(DOBAA) n ‐R F ], fluoroalkyl end‐capped N , N ‐dimethylacrylamide oligomer [R F ‐(DMAA) n ‐R F ], and fluoroalkyl end‐capped acrylic acid oligomer [R F ‐(ACA) n ‐R F ] in tetrahydrofuran under mild conditions. In these fluorinated oligomers, R F ‐(ACA) n ‐R F oligomer is more effective for the preparation of the corresponding oligomers/titanium dioxide nanocomposites, and this oligomer can afford the expected fluorinated titanium dioxide nanocomposites in higher isolated yields. In addition, R F ‐(ACA) n ‐R F /titanium dioxide composites are nanometer size‐controlled very fine nanoparticles (14–48 nm), and exhibited a good dispersibility not only in water but also in traditional organic solvents. Fluoroalkyl end‐capped oligomers/titanium dioxide nanocomposites were also applied to the surface modification of the common organic polymers such as poly(methyl methacrylate) to exhibit a good oleophobic and hydrophilic characteristics on the surface.
