(1) Most of the polysilazanes exist in the form of cyclic monomer or oligomer, and the high molecular weight polysilazanes with clear structure lack mature synthesis methods. Therefore, the exploration of mature high molecular weight polysilazanes synthesis methods has become a research hotspot in the future.
(2) N-methyl polysilazane is a semi-crystalline thermoplastic polymer with high resistance and surface energy, which has become a focus of attention in the field of silicone elastomer reinforcement.
(3) to strengthen the heat resistance and thermodynamic properties of polysilazanes. Synthesize polysilazanes with specific structure, improve the heat resistance and thermodynamic properties of polysilazanes, and provide a certain design idea and theoretical basis for the structure of polysilazanes with specific chemical properties.
