Preparation of silver/carbon fiber/polyaniline microwave absorption composite and its application in epoxy resin

Preparation of boron nitride nanosheet-coated carbon fibres and their enhanced antioxidant and microwave-absorbing properties

“…[1][2][3] As a form of carbon, carbon bres have been used as wave absorbers and reinforced llers in structural microwave-absorbing materials. 4 However, carbon bres are a strong radar reector against electromagnetic waves in the high-frequency range because of their low electrical resistivity (<10 À3 U m). 4,5 Carbon bres are also greatly susceptible to oxidation and can be oxidized at around 400 C. 6 Thus, much effort has been exerted to modify carbon bres with low-cost and light-weight coatings to improve their antioxidant property and microwave absorption property.…”

Microwave absorption properties of lightweight and flexible carbon fiber/magnetic particle composites

“…1,6 Carbon bers are also combined with other polymers, such as polyaniline and epoxy resin, to obtain absorbing materials in order to improve their microwave-absorbing capacity. 7,8 However, carbon materials are a type of electromagneticwave-absorbing materials that exhibit dielectric loss. When a pure carbonaceous material is used, the absorbing property of the material is 9,10 affected by its low magnetic loss and high reection coefficient.…”
