Özet

Polyimides embedding the nickelocene unit were prepared by in situ curing of poly(amic acid) macromolecules with nickelocene, for the molecular-level design of low-dielectric constant (IOW-kappa) materials. The effects of nickelocene on dielectric properties of polyimide are investigated in detail in this study. Nickelocene containing polyimides exhibit a number of desirable properties including low-water absorption and admirable thermal stability. Systematic studies demonstrate that proper insertion of nickelocene into a polyimide backbone can give rise to a reduction in the material's dielectric constant. All composites were subjected to DSC measurements for the purpose of examining microscopic miscibility. DSC thermograms of all composites showed only one T-g from all composition.
