A review on the mechanical, electrical and EMI shielding properties of carbon nanotubes and graphene reinforced polycarbonate nanocomposites

Abstract

Recently, it has been found that carbon nanotubes (CNTs) and graphene could prove to be the most promising carbonaceous fillers in polymers nanocomposites field because of their better structural and functional properties. Their uniform dispersion in polymer matrix leads to significant improvements in their several properties. This paper reviews the effect of nanofillers, ie, CNTs, derivatized CNTs, and graphene on the polycarbonate nanocomposite and its application in aerospace, automobile, sports, electronic sectors, and various industries. The comparative analysis of carbon‐based fillers on the different properties of polycarbonate nanocomposites is also included.

Free volume correlation with electrical conductivity of polycarbonate/reduced graphene oxide nanocomposites studied by positron annihilation lifetime spectroscopy

“…Polycarbonate (PC) is one of the most important engineering thermoplastics with good mechanical and thermal properties, impact strength, and optical transparency . Its electronic properties can be greatly improved by loading conductive fillers, for example, carbon black, graphite, carbon nanotubes, graphene, metallic particle, and so on. Among these conductive fillers, graphene has recently gained importance due to its high aspect ratio, small size, and excellent electrical conductivity .…”

Solid particle erosion resistance and electromagnetic shielding performance of carbon fiber reinforced polycarbonate composites

“…But the low solid erosion resistance of typical thermoplastics material limits its application. Continuous fibers such as glass fiber and carbon fiber were often added into the matrix to improve the solid erosion resistance and mechanical property of thermoplastics materials [18][19][20][21][22].…”

Synergistic effect of double percolated co‐supportive MWCNT‐CB conductive network for high‐performance EMI shielding application

“…CPCs have gained both research and industrial interest since the 1950s owing to their high flexibility, tunable electrical conductivity, simple fabrication methods, and so on. They are regarded as a significant group of comparatively inexpensive material to satisfy many engineering applications such as sensors, antistatic coatings and films, electrically conductive adhesives, electromagnetic and electric energy storage devices, thermal interface material, and also as an efficient EMI shielding material . Conventional polymeric materials are intrinsically insulating in nature and can be made conductive material by incorporating appropriate fillers that can render adequate electrical conductivity.…”

[7][8][9][10] Conventional polymeric materials are intrinsically insulating in nature and can be made conductive material by incorporating appropriate fillers that can render adequate electrical conductivity. Carbonaceous nanofillers, owing to their excellent electrical conductivity, are considered as a suitable filler to develop flexible CPC to fulfill the modern electronic demands.…”
