In the field of aerospace, Ferrocene is mainly used in rocket fuel additives and spacecraft coatings. In terms of spacecraft coatings, its vinyl derivatives form metal-containing polymers through olefin polymerization. The polymers have excellent properties such as high temperature resistance, oxidation resistance and radiation resistance, and can effectively protect spacecraft from operating safely in harsh space environments.

In the field of medicine, the application of Ferrocene is mainly concentrated in two aspects: drug synthesis and biosensors. In terms of drug synthesis, its derivatives can smoothly pass through the cell membrane due to their hydrophobicity, interact with enzymes, DNA, RNA and other substances in the cell, and thus play a therapeutic role. Some Ferrocene salts have been found to have anti-cancer activity, and its derivatives also show a variety of physiological activities such as bactericidal and anti-inflammatory, providing broad space for the development of new drugs. In terms of biosensors, its acid salts are widely used to modify oxidoreductases, such as glucose oxidase, to prepare amperometric glucose biosensors. This sensor has the advantages of high sensitivity, high selectivity and rapid response, and is of great significance for the diagnosis and monitoring of diseases such as diabetes.

In the field of agriculture, Ferrocene is mainly used in pesticide synthesis and agricultural mulch film additives. As an intermediate in pesticide synthesis, it can synthesize a variety of high-efficiency and low-toxic pesticides. Its derivatives have good insecticidal, bactericidal and weed control properties, can effectively prevent and control crop diseases and pests, and improve crop yields and quality. At the same time, it has less pollution to the environment and meets the requirements of green and environmentally friendly pesticides. As an agricultural mulch film additive, Ferrocene can prevent polyethylene from being degraded by light, extend the service life of the mulch film, and can be naturally degraded after a certain period of time, without causing soil residual pollution, which is conducive to the sustainable development of agriculture.

In the field of materials science, the application of Ferrocene is mainly concentrated in two aspects: electrochemical and photoelectric functional materials and single-walled carbon nanotube raw materials. It and its derivatives have good electrochemical activity and photoelectric properties, and can be used to prepare various functional materials, such as homogeneous multi-electron catalytic system materials, anion sensors, etc. In addition, by taking advantage of its easy sublimation characteristics, it can be used as a precursor to grow single-walled carbon nanotubes by methods such as chemical vapor deposition. Single-walled carbon nanotubes have excellent mechanical, electrical and thermal properties, and are important raw materials for the preparation of high-performance composite materials, nanoelectronic devices and energy storage materials, etc., and show broad application prospects in new energy battery electrode materials.

The core competitiveness of the Ferrocene system stems from its multi-dimensional product advantages. In terms of stability, Ferrocene derivatives are far more resistant to strong acids, alkalis and high temperatures than conventional organic materials, such as maintaining 90% of the initial performance after 1000 hours of 85℃/85%RH aging test in perovskite batteries.

Both economic benefit and environmental protection characteristics are the key to its industrialization and popularization. Compared to precious metal catalysts, FerroCENe-based materials cost up to 80% less, and the production process is free of heavy metal pollution. In the field of energy storage, adding 0.5wt %Ferrocene derivatives to the zinc battery electrolyte can increase the cycle life by three times, significantly reducing the unit energy storage cost. In terms of safety, its biocompatibility has passed the ISO 10993 medical device certification, and the blood compatibility index is better than that of traditional polyethylene materials in drug carrier applications.

The technical scalability advantage is particularly outstanding: the Ferrocene supramolecular system constructed by molecular self-assembly technology can integrate conductive, magnetic and catalytic functions at the same time, opening up a new path for the development of multifunctional composite materials. In terms of industrial applications, the existing production process can achieve 10,000-ton continuous production, and electronic grade products with a purity of 99.99% have met the needs of semiconductor manufacturing. With the further application of computational chemistry and machine learning in molecular design, the development cycle of Ferrocene derivatives has been reduced from the traditional trial-and-error model of 3-5 years to 6-12 months, continuing to promote the iteration of technological innovation.
