Abstract
Phosphogypsum is industrial waste that wastes a lot of land and pollutes the environment. In recent years, the application of phosphogypsum in polymers has become one of the research hotspots. In this paper, phosphogypsum/polystyrene composite was prepared by pretreatment, organic modification, and then mixed with polystyrene solution. It was found that phosphogypsum crystals had a highly orientation arrangement after pre treatment. Phosphogypsum exists as single crystal in polystyrene. Phosphogypsum has good dispersion and good interfacial properties in the polymerization. It provides guidance and reference for the application of phosphogypsum in polymer.
