Electromagnetic interference shielding nature of PVDF-carbonyl iron composites

Studying the effect of concentration factors on the process of chemical metallization of powdered polyvinylchloride

“…The problem with creating such composites is that to provide the required level of protection, a significant amount of filler material should be introduced in the polymer matrix to achieve percolation threshold [14][15][16]. The high concentration of filler not only increases the product weight and cost but also reduces the material manufacturability [17,18].…”

High-temperature dielectric and electromagnetic interference shielding properties of SiCf/SiC composites using Ti3SiC2 as inert filler

“…The electromagnetic radiation can seriously affect the function of nearby wide range of electrical circuitry and cause potential health hazards for human beings when exposed to the electromagnetic fields [3,4]. Therefore, various materials such as metal-based materials, carbon-based materials [5,6] and conducting polymer-based materials [7,8] have been developed for the attenuation of EMI during the past decades. Metal-based materials in the form of thin sheets or sheathing typically serve as excellent EMI shielding agents, but the disadvantages of heavy weight and prone to environmental degradation often make them undesired choices for many current devices [9].…”

Influence of heat treatment on electromagnetic properties of polyimide/carbon black composites

“…Nowadays, much attention has been paid to fabricate a kind of absorbing materials to solve the problems of traditional microwave absorbing materials that cannot use at high temperature, low mechanical properties, heavyweight, the narrow absorption bandwidth, and so on . Among them, polymer radar absorbing material not only can combine the properties of the polymer matrix but also can use different fillers to provide the necessary electromagnetic performances to reduce or weaken electromagnetic wave, which have attracted much interest because of their extensive applications in microwave absorption .…”
