▎ 摘 要
A novel core-shell structured mica-titania@graphene antistatic composite pearlescent pigment has been designed for electrical industry. The transparent conductive graphene shell was introduced on the mica-titania surface to decrease electrical resistivity of pearlescent pigment while keeping its original color effect. The composite pigment samples with silver white pearlescent effect, as well as that of raw mica-titania pigment, were obtained by co-precipitation method and annealed under argon atmosphere. The stability of titanium chemical state and graphene oxide reduced after annealing have been proved by Raman and X-ray photoelectron spectroscopy successfully. The best antistatic property of as-prepared composite pigments has been proved to increase 14 times than that of MT pigment. Our mica-titania@graphene antistatic composite pearlescent pigment could enrich the family of pigments and provide a new design for functional pearlescent pigment. (C) 2016 Elsevier Ltd.
