| Abstract: | Oxygen plasma was used to modify the copper phthalocyanine (CuPc) blue pigment. It is effective in improving stability of CuPc pigment in aqueous dispersion. Treatment conditions, e.g., treating time, gas pressure and discharge power, had great influence on the surface properties of pigments. X-ray photoelectron spectroscopy (XPS) indicated that the CuPc blue pigment surface was partially oxidized and polar groups including COH, COOH, C?O were incorporated. Dispersion stability of pigment in water was greatly increased. The plasma modified CuPc blue pigment was applied to on cotton fabric. Rubbing fastness and K/S value of the pigment prints were enhanced. |
