“…In comparison to EDX, CHNS and ICP-OES analyses are more adequate for quantitative chemical analysis; therefore, an oxygen content of 4.77 mass% was determined using the total mass of materials minus the detected elements of the CHNS and ICP-OES analysis. These values are in good agreement with the recent literature [31,32,[59][60][61][62][63]. It is expected that the detected oxygen and hydrogen atoms mostly belong to surface functionalities like carboxylic, ketonic, or hydroxylic groups [40].…”

“…Surface uniformity is prerequisite for a high surface loading. Surface homogeneity and reactivity enhancement was achieved by the gas phase reaction of ND with hydrogen, fluorine and chlorine [118]. The modification of chlorinated ND surfaces was achieved by hydroxyl, carbon fluoride and amine groups [119].…”

In this review, an overview of various types of nanofillers is presented with special emphasis on structure, synthesis and properties of carbon nanotube (CNT), nanodiamond (ND) and nanobifiller of CNT/ND, CNT/GO and CNT/graphene. In addition, polymer/CNT, polymer/ND and polymer/nanobifiller composites have been discussed.The efficacy of different fabrication techniques for nanocomposites (solution casting, insitu and melt blending method) and their properties were also discussed in detail. Finally, we have summarized the challenges and future prospects of polymer nanocomposites reinforced with carbon nanofillers hoping to facilitate progress in the emerging area of nanobifiller technology. INTRODUCTIONAmong the unique properties of polymer/nanomaterials, large surface to volume ratios and mechanical properties are noteworthy. These properties offer several exciting areas of research. The ultra high stiffness and hardness exhibited by nanomaterials make them important in reinforcing polymer matrices. According to recent research small additions of nanomaterials (~ 1 wt. %) may remarkably increase the mechanical properties (upto100%) although the precise mechanism responsible for the dramatic enhancement is not clearly understood [1,2]. It is generally believed that nanomaterials and polymer matrices develop molecular interactions which play a major role in enhancement. The key which hold true for the enhancement in mechanical properties is large surface area available for such interactions.In recent years variety of nanomaterials were synthesized and characterized, among them nanocarbons are of particular interest with different dimensionalities e.g. graphene, nanotubes and nanodiamond with dimensionalities two, one, and zero respectively [3,4].The mechanical properties of the polymer matrices reinforced with one type of nanocarbons have been extensively investigated [5]. Nature of interaction of nanocarbons constituents with polymer matrix depends on the dimensionality of filler constituent. For example the nanodiamond (ND) may interact with polymer at a point Downloaded by [New York University] at 14:08 04 August 2015 3 whereas carbon nanotubes (CNT) may interact over the length of polymer chain. However mechanical properties of polymer matrix have been known to improve by different type of nanocarbons. The synergistic effect in properties of final composite may be achieved by the incorporation of two types of nanocarbons, where each of them interacts differently with the matrix. CNT offers venues of exciting areas of research since Iijima initially identified CNT structure in 1991. CNT have unique thermal, electrical, mechanical and magnetic properties, high surface area, low density and high chemical stability. The diameter of the CNT usually ranges from 0.4-4 nm. The length of the nanotubes can vary from 100 nm to several micrometers depending on the preparation and purification methods used. Their uses are being extensively investigated for polymer composites, field emission displays, fabrication of reinforc...

“…In order to homogenize the surface it is either possible to oxidize [27] or reduce [19,28] these moieties to COOH or OH groups, respectively. However, for the goal of covalent C-C coupling these techniques are not applicable as these groups hamper the desired process.…”
