Microstructure and Dielectric Properties of Poly(aryl ether ketone)s/Tetra-amino-phthalocyanine Zinc Composites

Three series of CNPAEK/4NH2-ZnPc (tetra-amino-phthalocyanine zinc), 2CNPAEK/4NH2-ZnPc and SAPEK/4NH2-ZnPc composites were prepared. The CNPAEKs/4NH2-ZnPc composites have spherical shape, and the diameter of particulates is nonuniformly about 1–5 µm, and 2CNPAEK/4NH2-ZnPc and SAPEK/4NH2-ZnPc composites exhibit diameter of spherical shape is about 100 nm. This can be attributed to SPAEK and 2CNPAEK show stronger polarity than CNPAEKs, and have stronger interaction with 4NH2-ZnPc. Different polarity make the 4NH2-ZnPc particles distribute more uniformly in the matrix and obtain smaller size in the order of SAPEK, 2CNPAEK and CNPAEK. Consequently, the SPAEK/4NH2-ZnPc composite exhibits better dielectric properties than CNPAEK/4NH2-ZnPc and 2CNPAEK/4NH2-ZnPc composites.
