Polystyrene grafted carbon black synthesis via in situ

DENKA BLACK/polystyrene nanocomposites (DB/PS) were successfully prepared through a facile strategy. Some of the styrene molecules were grafted and polymerized onto the surface of the DB via the in situ free radical addition process in ionic liquid, and others self-polymerized and coated on the polystyrene grafted DB. The ionic liquid improves the grafting percentage because of its high

Thermal Conductivity of Graphite

Different conductive fillers such as metal powder, carbon black, carbon nanotubes (CNTs) and natural graphite were employed as reinforcing fillers of various polymeric materials [5, 6]. Amongst all these fillers, graphite garnered in much interest owing to its unique properties such as abundant availability, low cost and easy functionalization [ 7 ].

Mechanisms of mechanical reinforcement by graphene

The majority of the early studies on nanocarbon composites were conducted using CNTs with research upon graphene and graphene-based nanocomposites having taken place only since its first identification and isolation in 2004. 3 Nevertheless, the extensive research studies on the GRM-based materials have now led to a better understanding of the fundamental properties for all of these sp 2 materials.

Synergetic Effect of Discontinuous Carbon Fibers and

Abstract Aluminum (Al) matrix composite materials reinforced with graphite flakes (GF) and pitch-based carbon fibers (CF) were fabricated by solid–liquid phase sintering with a small amount of Aluminum–Silicon eutectic alloy (Al-12 wt%Si). The amount of Al–Si is optimized for a carbon content of 50 vol% in order to achieve, in the plane of GF reinforcement, a higher thermal conductivity

Graphene

Graphene (/ ˈ ɡ r f iː n /) is an allotrope of carbon consisting of a single layer of atoms arranged in a two-dimensional honeycomb lattice. The name is a portmanteau of graphite and the suffix -ene, reflecting the fact that the graphite allotrope of carbon consists of stacked graphene layers.

Carbon nanofibres (CNFs) and graphite flake microparticles were added to thermoplastic polystyrene polymer with the aim of making new conductive blends suitable for 3D‐printing. Various polymer/carbon blends were evaluated for suitability as printable, electroactive material.

Reinforced carbon–carbon

Carbon fibers are also composited with other materials, such as graphite, to form reinforced carbon-carbon composites, which have a very high heat tolerance. The disc is usually made of cast iron, but may in some cases be made of composites such as reinforced carbon–carbon or ceramic matrix composites. Furthermore, disk brake systems of airplanes and racing cars are using carbon/carbon

Carbon black

Carbon black (subtypes are acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of heavy petroleum products such as FCC tar, coal tar, or ethylene cracking tar. Carbon black is a form of paracrystalline carbon that has a high surface-area-to-volume ratio, albeit lower

Graphite Mineral

It (carbon) fiber and carbon nanotubes are also used in carbon fiber reinforced plastics and heat-resistant composites such as reinforced carbon-carbon (RCC). Commercial structures made of carbon fiber graphite composites include fishing rods, golf club shafts, bicycle frames, sports car body panels, the body of the Boeing 787 Dreamliner and the body of the pool marker bars.

In recent decades, the intense research in the area of polymer composites has motivated a great interest towards carbon-based materials including carbon black, carbon nanotubes, graphite or graphene. One type of carbon particle, carbon black, has been used for a long time in the rubber industry to prepare composites with greatly improved properties with regard to the unfilled polymer.
