Functional nano graphene conductive resin modified filler for absorbing waves: revolutionary technological progress

Composite absorbing materialThe rapid development provides a guarantee for the research and development of structural absorbing materials. New thermoplastic PEEK, PES, PPS, as well as thermosetting epoxy resins, bismaleimide, polyimide, polyetherimide, and isocyanates, all have good dielectric properties, and composite materials made from them have good radar transmission and transparency.
In recent years, a large amount of improvement work has been carried out on carbon fiber abroad, such as changing the cross-sectional shape and size of carbon fiber, surface treatment of carbon fiber surface, and improving the electromagnetic properties of carbon fiber for use in absorbing structures.

Scientists have discovered that radar operates in the microwave frequency range and can be absorbed by multi walled nanotubes (MWNTs). Applying MWNT to aircraft will result in radar absorption, thus having a smaller radar cross-section. According to the scientific community's argument, carbon nanotubes are used as stealth technology for airplanes. It has been found that in addition to absorbing radar properties, nanotubes neither reflect nor scatter visible light, making them almost invisible at night. This is similar to the current practice of painting stealth planes black, but with better results. However, current manufacturing limitations mean that the production of nanotube coated aircraft is impossible. In addition, research at home and abroad has shown that the absorption performance of carbon nanoparticles is limited by their intrinsic structure, making it difficult to achieve wideband stealth effectsGraphene materialHaving adjustable molecular structure and bandgap, it has great potential.

Functionalization of Advanced Institute Technology Research and DevelopmentGraphene absorbing stealth fillerWith almost no increase in weight, it can be used to fuse composite materials with resins, endowing the body material with radar transmission and transparency, forming a structural absorbing material.

After years of research and development, Advanced Institute Technology has applied for a process patent for graphene conductive enhanced absorbing fillers. This process enables graphene absorbing materials to be functionalized through a plasma reactor - even if they can be combined with other materials, thus utilizing the characteristics of graphene and other nanomaterials to give ordinary materials the superpowers of graphene absorbing materials.
