Organosilicate compounds have many unique and excellent physical and chemical properties, which has long attracted widespread attention, and the study of polysilazanes with Si-N bond structure has also made great progress in recent decades. Although the research focus of polysilazanes is only in ceramic synthesis, high temperature resistant silicone rubber and composite materials, its potential applications in coatings are also becoming more and more popular. Polysilazanes contain silicon-nitrogen bonds and nitrogen-hydrogen chains, these chemical bonds endow it with many specific properties, and organosilicate compounds have many unique and excellent physical and chemical properties, which has long attracted widespread attention, and the study of polysilazanes with Si-N bond structure has also made great progress in recent decades.
