摘要：

In this work, cellulose acetate-La(OH)(3) nanocomposites were synthesized via two different in situ and ex situ sonochemical methods. At ex situ firstly lanthanum hydroxide nanostructures were synthesized via sonochemical reaction. The effect of different parameters such as power, time, and surfactants on the morphology of La(OH)(3) nanostructures was investigated. Nanostructures were characterized by XRD and SEM. The influence of La(OH)(3) nanostructures on the flame retardancy of the cellulose acetate matrix was studied using UL-94 analysis. The enhancement of fame retardancy of nanocomposite is due to endothermically decomposition of La(OH)(3) that absorbs energy and simultaneously releases of water.
