摘要
The novel optically active poly(amide–imide) (PAI)/TiO2 nanocomposites containing fluorene moieties have been successfully synthesized through ultrasonic irradiation. The surface of nanoparticles was chemically modified with γ-aminopropyltriethoxyl silane to enhance the compatibility with polymeric matrix and to avoid the aggregation of nanoparticles. The dispersion of surface-modified TiO2 in PAI film was confirmed by the transmission electron microscope (TEM) analysis showing the well-dispersed nanosized TiO2 nanoparticles. The thermal stabilities and optical properties of PAI/surface-modified TiO2 nanocomposite films were also investigated. The thermogravimetric analysis data showed an improvement of thermal stability of novel nanocomposite films as compared to the pure polymer.
