AbstractThe synthesis of reflective silvered polyimide films by a single-stage auto-metallization process entailing the (hexafluoroacetylacetonato)silver(I) complex dissolved in solutions of poly(amic acid)s and polyimides formed from 2,2-bis(3,4-dicarboxyphenyl)hexafluoropropanedianhydride (6FDA) and 2,2-bis(4-(4-aminophenoxy)hexafluoropropane (4-BDAF) is described. Heating cast silver(I)-poly(amic acid)/polyimide films effects silver(I) reduction and nanoaggregation giving reflective films for Ag concentrations from 6-10 wt %. A6% silver film gives specular reflectivies greater than 80%. Films prepared from the soluble fully imidized form of 6FDA/4-BDAF were less reflective.

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.
