Abstract: The high strength, high modulus, high thermal stable properties, and special functionalized methods of bisphthalonitrile polymers are discussed. The functional design on chemical reaction of polymer systhesis is mainly studied through some special bisphthalonitrile monomer. The thermosetting resin which is easy to process and convenient to cure could be supplied as the high performance matrix resin. The ferrocene group was bonded to bisphthalonitrile resin by molecure structure design methods. The cured polymer exhibits good electrochemistry properties. The polymer magnetic materials with courier temperature beyond 300oC was obtained. The magnetic functional composites containing organic-inorganic hybrid materials were obtained according to the reactivity between bisphthalonitrile and metal or metal salt. The nano functional composite materials were prepared by the surface nitrilized of carbon nanotubes. The hyperbranch Cu-phthalocyanine with high permittivity and PEN dielectric film with high strength were realized by the chemical control systhesis. The electric, magnetic, and shear stress field influences of polymer microstructure are studied. These functionalized research efforts broad the research, development and application region of the bisphthalonitrile polymer.
