Abstract

Based on the study of the structural characteristics of pigments and fillers and the action principle of dispersants,the molecular structures of acrylic acid,polyurethane,epoxy and other waterborne dispersants were analyzed.The anchoring groups and hydrophilic segments in common dispersants were summarized,and the idea of molecular design of dispersants was put forward.

Key words

dispersant;pigments;molecular design
