“…These properties of CNTs endow themselves with new scientific and technological opportunities as an ideal filler material in composites. To date, various composite materials have been prepared by incorporating SWNTs or MWNTs into a metal matrix [9][10][11][12], a ceramic matrix [13][14][15][16] or a polymer matrix [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33]. Polymers can be easily processed and fabricated into intricately shaped components without damaging CNTs during processing using conventional methods, and hence the manufacturing cost can be certainly reduced.…”

Abstract. The state-of-art and key problems of carbon nanotube (CNT) based polymer composites (CNT/polymer composites) including CNT/polymer structural composites and CNT/polymer functional composites are reviewed. Based on the results reported up to now, CNTs can be an effective reinforcement for polymer matrices, and the tensile strength and elastic modulus of CNT/polymer composites can reach as high as 3600 MPa and 80 GPa, respectively. CNT/polymer composites are also promising functional composite materials with improved electrical and thermal conductivity, etc. Due to their multi-functional properties, CNT/polymer composites are expected to be used as low weight structural materials, optical devices, thermal interface materials, electric components, electromagnetic absorption materials, etc. However, the full potential of CNT/polymer composites still remains to be realized. A few key problems, such as how to prepare structurecontrollable CNTs with high purity and consistently dependable high performance, how to break up entangled or bundled CNTs and then uniformly disperse and align them within a polymer matrix, how to improve the load transfer from matrix to CNT reinforcement, etc, still exist and need to be solved in order to realize the wide applications of these advanced composites.

“…Therefore, the prospects for application of these materials in various areas are diverse [1][2][3]. In the last few years CNT and CNF are intensively studied for development of composite materials, in particular, based on polymer [4,5] and metal matrices [6,7]. Even wider application of carbon nanomaterials is impeded by their susceptibility to oxidation at moderate and high temperatures in the oxidative environments.…”

A new method for synthesis of CNT-SiO 2 composite was developed. Oligomethylhydridesiloxane (OMHS) was used as the SiO 2 precursor. The presence of active hydrogen in the composition of OMHS made it possible to obtain chemical interaction between the surface of carbon nanotubes and the deposited silica layer. The effect of the silica film on the CNT oxidizing ability was studied. It was found that the oxidation rate of the CNT-SiO 2 composite decreases approximately by an order of magnitude in comparison with as-prepared CNT. The morphology and structure of amorphous silica obtained after oxidation of the CNT-SiO 2 composite were studied. The thermal stability of the CNT-SiO 2 composite was also studied. The CNT-SiO 2 composite was found to be thermally stable up to temperatures of 1100-1200 ºC. An increase in the calcination temperature to 1300 ºC leads to segregation of the CNT-SiO 2 composite into individual components: CNT and SiO 2 particles.

“…It was found that the CNTs were aligned along the extrusion direction and were strong enough to withstand the extrusion load. Rolling of Cu-CNT composites resulted in alignment of CNT clusters in the matrix [67,77,80]. Improvement in wear resistance and coefficient of friction was also observed in rolled samples [83].…”

“…However, the approach was mainly confined to Cu-CNT [41,71,[77][78][79][80] and Al-CNT [29,30,[81][82][83][84][85][86] composites. Kuzumaki et al [29] have synthesized Al-CNT composite through hot extrusion of powder compacts, at 873K.…”
