Highly Aqueous-dispersible Carbon Black Grafted with SAS and AA Copolymers

Abstract Carbon black grafted with copolymer of AA and SAS exhibits significant dispersibility in water. Although the grafting ratio is low, sulfonic groups of SAS can effectively stabilize carbon black when dispersed in aqueous media. The advantage of this method is that only low grafting ratio is needed, thus avoiding the complex procedure for high grafting ratio.
