Preparation and Characterization of AlOOH/Polyimide Nanocomposite Membrane

Abstract:

Using metallurgical grade aluminum hydroxide as the raw material self-dispersed g-AlOOH nanopowders were made by sol-hydrothermal crystallization and the charge process. The AlOOH/polyimide nanocomposite membrane was prepared by compounding soluble polyamide with AlOOH using sol dispersed quasi-homogeneous blending and compounding method. TEM, XRD, IR and other techniques were employed to characterize AlOOH nanopowders and AlOOH/polyimide nanocomposite membranes, respectively. The results showed that: the particle size of AlOOH crystal was about 70nm, with good self-dispersion in water and some organic solvents; in the polyimide matrix, the AlOOH was dispersed at nanoscale, without agglomeration; when its content in composite membrane reached 15 %, it still had a good dispersion and transmission property.
