The specific application cases of polysilazane are as follows:Aerospace field
Thermal protection coating: Coating the hot end components of aircraft engines, heat-resistant tiles of spacecraft, etc. with polysilazane. At high temperatures, polysilazane can be converted into ceramic materials such as SiCNO, SiCN, or SiO ₂, which can withstand extreme high temperature environments and effectively protect aircraft from high temperature erosion during high-speed flight and re-entry into the atmosphere.
Manufacturing of structural components: After solidification, polysilazane has high hardness and strength, as well as a certain degree of flexibility, which can be used to manufacture structural components such as wings and fuselage of aerospace vehicles, helping to reduce the weight of the aircraft, improve its performance and fuel efficiency.
Electronic packaging and insulation: With excellent electrical insulation performance, polysilazane can be used to manufacture packaging materials, insulation materials, etc. for aerospace electronic equipment, ensuring the normal operation and safety of electronic devices.
Automotive field
Exhaust pipe protection: Exhaust pipes of cars and trucks are often exposed to high temperature environments. Coating the surface of the exhaust pipe with polysilazane can effectively improve its high-temperature corrosion resistance and extend the service life of the exhaust pipe.
Piston protection: Polysilazane can form a protective film on the surface of the piston, which can withstand high temperatures and friction during piston operation, reduce wear and corrosion, and improve the performance and reliability of the piston.
Heat exchanger coating: Applied to the surface of heat exchangers, polysilazane coating can prevent corrosion of heat exchangers in high temperature and complex working environments, ensuring heat exchange efficiency.
Electronic field
Optical coating: Coating the surface of optical lenses with a polysilazane anti reflective coating can reduce light reflection, improve the transmittance of the lens, and make the visual effect clearer. In addition, it can also be used to prepare optical waveguide materials, which have good optical uniformity and low loss characteristics, and have potential application prospects in the field of optical communication.
Microfluidic chip coating: A uniform polysilazane coating is formed on the surface of microfluidic chips through chemical vapor deposition and other methods, which can accurately control the hydrophilicity or hydrophobicity of the chip surface, optimize the flow characteristics of fluids in microchannels, reduce liquid adsorption and residue, and improve the performance and reliability of microfluidic chips.
Environmental protection field
Wastewater treatment: Polysilazane can be used to prepare adsorption materials for wastewater treatment, and its special structure can have good adsorption performance for heavy metal ions, organic pollutants, etc. in wastewater. By loading polysilazane onto porous materials, the adsorption capacity and selectivity of the adsorbent material can be improved.
Air purification: can be used to prepare air filtration materials, effectively filter harmful gases and particles in the air, and improve air quality.
Fabric field
Polysilazane can form a soft coating on the surface of fabric fibers, reducing the friction coefficient between fibers and making the fabric feel softer and smoother. Moreover, this softness effect is long-lasting and will not disappear quickly due to fabric use or washing. It can also prevent adverse phenomena such as hardening of the fabric during long-term use, and meets environmental protection requirements
