In terms of optoelectronic performance, the new type of σ - π conjugated polysilazane is one of the research hotspots. By introducing electron rich functional groups (such as alkynyl, aryl, arylamino, etc.) into the main chain of polysilane, a unique optoelectronic property can be achieved by constructing a σ - π conjugated polysilazane based on alternating rigid conjugated units and Si-N flexible chain structures. Research has found that the optoelectronic properties of this type of polysilazane in solution and solid states are closely related to its molecular structure, such as the main chain conjugation system and side chain substituents, which can affect its photophysical properties such as maximum absorption wavelength, maximum emission wavelength, fluorescence quantum efficiency, third-order nonlinear optical coefficient, as well as its electrochemical properties such as redox potential. The relevant research has opened up new avenues for the development of novel organic optoelectronic functional materials.
In terms of market and industry, the global market size of polysilazane is constantly growing, with a total of approximately 20.5 billion yuan in 2022. In 2023, the global market revenue of polysilazane reached 26.33 million US dollars, and it is predicted to surge to 119.42 million US dollars by 2030, with a compound annual growth rate (CAGR) of 19.08% during this period. However, the production capacity of the polysilazane industry is relatively low and concentrated among European and American companies. Merck Group in Germany is a leading enterprise in the industry, occupying over 80% of the market share. In 2013, polysilazane entered the field of view of domestic enterprises. Currently, there is a small batch production capacity in China, but compared with foreign countries, there is still a gap in research and development capabilities and the ability to transform scientific and technological achievements.
In terms of preparation and storage, the preparation method of polysilazane is not yet perfect, the reaction products are complex, and the molar mass is low. It usually needs to be prepared and stored under harsh conditions such as anhydrous and anaerobic conditions, because most polysilazanes are relatively active and have high reactivity with water, polar compounds, oxygen, etc., which makes their storage and transportation difficult. For example, special packaging and storage conditions are required during storage to prevent it from reacting with external water and oxygen.
In terms of special applications: In addition to common applications such as ceramic precursors, coating materials, resin materials, etc., polysilazane also has potential applications in some special fields. For example, in terms of electrolyte additives for lithium batteries, polysilazane can improve the performance of the electrolyte, enhance the charging and discharging efficiency and cycling stability of lithium batteries. In microelectromechanical systems (MEMS), polysilazane can be used to prepare ceramic MEMS components, utilizing its high temperature stability and good formability to produce micro ceramic components with high precision and performance.
