The road of counterattack from laboratory to industrial application
In the vast universe of materials science, there is a substance as mysterious and powerful as a "Transformers", and that is polysilazane. This compound, which sounds like an element from a science fiction movie, is actually a "magic net" woven by scientists using silicon (Si) and nitrogen (N) atoms. It can withstand high temperatures of 3000 ℃, strong acid and alkali corrosion, and even switch between organic and inorganic forms freely like a chameleon.
The 'versatile elf' in the laboratory
The "deformability" of polysilazane comes from its unique molecular structure: the silicon nitrogen main chain acts like a skeleton, while the organic groups on the side chains (such as methyl and vinyl) act like flexible joints. By adjusting the types and quantities of these "joints", scientists can transform them into high-temperature resistant coatings, anti-corrosion coatings, or insulation layers for semiconductor chips. What's even more amazing is that by heating it to 800 ℃, it can undergo a complete transformation into silicon nitride ceramics with a hardness comparable to diamond, becoming the "armor" of aircraft engine blades or nuclear reactor components.
Cross disciplinary stars in the industrial sector
In industrial applications, polysilazane can be regarded as a "cross-border expert". Automobile manufacturers use it to spray a layer of invisible shield on the engine, allowing corrosive gases after fuel combustion to enter without holes; Architects use it to coat glass curtain walls with a layer of "lotus leaf film", which falls at the touch of rainwater and leaves no place for dust to hide; Even the precision components on spacecraft rely on the thermal protection layer it provides to safely re-enter the atmosphere.
Future: From 'Materials' to' Life '
Scientists have even attempted to introduce polysilazane into the field of biology, using its high strength and biocompatibility to repair fractures, encapsulate drugs, and even simulate the microstructure of human bones. Perhaps in the near future, it will become the "invisible wing" for humans to explore the universe and fight against diseases.
