Phthalocyanine Polymer Magnetic Composites

Magnetic materials are one of time-honored research fields in materials science and have wide applications in information materials, industrial control, electronic devices, biotechnology and catalysts, which creates the widespread and vibrant research interests in academic and industrial fields. However, with the increasing advancements in materials science, conventional magnetic materials have the problems of poor processability and easy oxidation at high temperature resulting generally in loss of magnetism, combined with tendency of agglomeration in nanosacle.Give these disadvantages above-mentioned, we have systematically studied novel high temperature resistant polymer magnetic composites on the basis of surface chemical functionalization of inorganic fillers together with versatile chemical reactivity and high temperature resistance, high modulus and high strength of phthalocyanine polymer. Preparation, structure characterization and materials application of the functional composites are included in this dissertation and the main research can be divided into following aspects:1. Preparation of magnetic iron phthalocyanine polymer matrix via the polymerization of bisphthalonitrile with iron pentacarbonyl based on the intrinsic properties of phthalocyanine cycle structures.2. Preparation of organic-inorganic materials through surface chemical functionalization of inorganic fillers. Initially, chemical reaction mechanism between magnetic prepolymer matrixes with functional coatings of iron carbonyl was studied with the assistance of synthesized model compound. And then, high temperature resistant magnetic composites based on phthalocyanine polymer were successfully prepared via the interfacial reaction.3. Preparation and characterization of magnetic functional Fe-Pc/Fe nanocomposites based on the interfacial reactions between carboxyl group and Fe2+ and between benzoxazine and phthalonitrile prepolymer.
