【 摘 要 】

A series of ultra-thin films were prepared by dip-coating method, with the copolyester-TiO2 nanocomposites as solute and chloroform-trifluoroacetic acid as solvent. The thickness, surface morphologies and thermal properties of the films were studied. The results indicated that the thickness of the ultra-thin films was improved with the increase of the concentration of solution. The glass transition temperature declined from 64.2 °C to 51.2 °C with the decrease of film thickness from 3.275 μm to 22 nm.
