“…Since our initial work, the protocol of adding a bulky side chain to the SWNT ends via amide or ester bond formation (Scheme 4) has been applied by other groups, [85][86][87][88][89][90][91][92] thus establishing the generality of the process.…”

In this Account we highlight the experimental evidence in favor of our view that carbon nanotubes should be considered as a new macromolecular form of carbon with unique properties and with great potential for practical applications. We show that carbon nanotubes may take on properties that are normally associated with molecular species, such as solubility in organic solvents, solutionbased chemical transformations, chromatography, and spectroscopy. It is already clear that the nascent field of nanotube chemistry will rival that of the fullerenes.

“…Khare et al (2002) developed hydrogenated CNTs using electric discharge. Sun et al showed that the esterification of the carboxylic acid groups could also be used to functionalize and solubilize nanotubes of any length (Riggs et al 2000;Sun et al 2001;Fu et al 2001). Wilson et al illustrated the use of anilines to functionalize nanotubes (Sun et al 2001).…”

Effective utilization of carbon nanotubes (CNTs) as reinforcements in composites necessitates good interfacial bonding with the surround matrix material. The covalent functionalization of CNTs is an effective method to enhance this bonding. However, covalent bonds introduced by a functional group may alter the pristine structure of the CNT and lower its mechanical properties. Here we study the effect of hydrogen (-H), hydroxyl (-OH), carboxyl (-COOH), and amine (-NH 2 ) functionalization on Young's modulus of a single-wall CNT (SWCNT) using molecular mechanics (MM) simulations with the MM3 potential and the software TINKER. Both pristine and functionalized SWCNTs have been deformed in simple tension. From the strain energy of deformation vs. the axial strain curves, the value of Young's modulus has been derived as a function of the functionalization group and the amount of functionalization. It is found that Young's modulus decreases by about 30 % with 20 % of functionalization, the reduction is essentially proportional to the increase in the percentage of the functionalization material and is nearly the same for each of the four functional groups studied.

“…A previous study showed that cracks fail to propagate because of grain mismatch and the consequent poor bonding between the nano-carbon black and the ceramic phase (Riggs et al 2000). …”

“…Besides, the use of carbon nanofillers in polymer can increase the hardness depending on the carbon structure. Therefore, small additions of CNTs and CNFs to different materials can considerably improve their mechanical and electrical properties (Riggs et al 2000;Jong and Geus 2000;Wagner et al 1998). CNT/CNF reinforced cement composites are able to provide electromagnetic interference shielding (Fu and Chung 1996) and are also capable of nondestructive flaw detection (Chen and Chung 1993).…”

The aim of this study was to explore the incorporation of biomass carbon nanofillers (CNF) into advanced ceramic. Biomass from bamboo, bagasse (remains of sugarcane after pressing), and oil palm ash was used as the predecessor for producing carbon black nanofillers. Furnace pyrolysis was carried out at 1000 °C and was followed by ball-mill processing to obtain carbon nanofillers in the range of 50 nm to 100 nm. CNFs were added to alumina in varying weight fractions and the resulting mixture was subjected to vacuum sintering at 1400 °C to produce nanobioceramic composites. The ceramic composites were characterized for mechanical, thermal, and morphological properties. A high-resolution Charge-coupled device (CCD) camera was used to study the fracture impact and the failure mechanism. An increase in the loading percentage of CNFs in the alumna decreased the specific gravity, vickers hardness (HV), and fracture toughness values of the composite materials. Furthermore, the thermal conductivity and the thermal stability of the ceramic composite increased as compared to the pristine alumina.
