Abstract
Three series of CNPAEK/copper phthalocyanine (CuPc), 2CNPAEK/CuPc and sulfated poly(aryl ether ketone) (SPAEK)/CuPc composites were prepared using a solution blending technique. The CNPAEKs/CuPc composites have a spherical shape with a diameter range of 1–5 μm, although 2CNPAEK/CuPc and SPAEK/CuPc composites have a spherical shape with a diameter ∼100 nm because SPAEK and 2CNPAEK exhibit stronger polarities than CNPAEK, resulting in better interphase interactions with metallophthalocyanine. The degree of dispersion and the size of the CuPc particles in the matrix decreases in the following order: SPAEK>2CNPAEK>CNPAEK. The SPAEK/CuPc25 composites exhibit better dielectric properties than either the CNPAEK/CuPc or 2CNPAEK/CuPc composites, with a dielectric constant >400 at 100 Hz and a dielectric loss <0.5.
