Efficient preparation of novel fluoroalkyl end-capped oligomers/titanium dioxide nanocomposites
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-RF], fluoroalkyl end-capped N,N-dimethylacrylamide oligomer [RF-(DMAA)...

| description | 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-RF], fluoroalkyl end-capped N,N-dimethylacrylamide oligomer [RF-(DMAA)n-R F], and fluoroalkyl end-capped acrylic acid oligomer [RF- (ACA)n-RF] in tetrahydrofuran under mild conditions. In these fluorinated oligomers, RF-(ACA)n-RF 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, RF-(ACA)n-RF/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 nano-composites were also applied to the surface modification of the common organic polymers such as poly(methyl methacrylate) to exhibit a good oleophobic and hydro-philic characteristics on the surface. © 2008 Society of Plastics Engineers. |
