Etal C2 Ceramide site substrates that avoids the have to have for higher temperatures and may be performed at temperatures as low as 80 C. Open-ended CNTs were straight bonded onto Cu and Pt substrates that had been functionalized working with diazonium radical reactive species, as a result enabling bond formation with all the openended CNTs. Cautious control throughout grafting of your organic species onto the metal substrates resulted in functional group uniformity, as demonstrated by FT-IR analysis. Scanning electron microscopy images confirmed the formation of direct connections involving the vertically aligned CNTs and the metal substrates. Additionally, electrochemical characterization and application as a sensor revealed the nature from the bonding among the CNTs and the metal substrates. Keywords and phrases: carbon nanotubes; metal arbon interface; bond formation1. Introduction Carbon nanotubes (CNTs) are macromolecules whose discovery, arguably attributable to Professor Sumio Iijima [1,2], has offered heretofore unimagined prospective for engineering applications. CNTs have garnered immense research interest mainly because of their unique structure and physical properties [3]. In the nanoscale level, they exhibit very high strength and electrical and thermal conductivities [6]. Single-walled CNTs have been shown to have a Young’s modulus of higher than 1 TPa [9], with an electrical resistivity as low as three 10-7 m [10] and a thermal conductivity as high as 3000 Wm K-1 [11,12]. Moreover, CNTs have already been reported to possess a large ampacity compared with metals, suggesting their untapped potential in electronics [13]. Also, the heat dissipation capabilities of CNT arrays as thermal interfaces have already been demonstrated [14]. Numerous researchers have attempted to prepare CNT/Cu composites with varying degrees of good results [157], but to be able to reap the benefits of CNTs’ physical properties, important efforts have already been devoted to increasing CNTs on metal substrates so that you can obtain chemical bonding [180]. Chemical vapor deposition (CVD) has been adopted because the most helpful and suitable system for synthesizing vertically aligned CNTs on metals, but classic CVD requires temperatures above 650 C to make high-quality CNTs. It has been reported that higher temperatures negatively have an effect on the lifetime from the catalyst nanoparticles by advertising catalyst ripening, carbide formation, alloying, and coarsening [21,22].

High-density CNT arrays that can assistance interconnections have already been developed [246]. Having said that, the inventive approaches essential to synthesize CNTs directly on metal substrates, including Cu, Al, Ti, Ta, and stainless steel, demonstrate the challenges involved in expanding highquality CNTs [18,268]. In addition, experimental metal alloy combinations for interfacing via standard soldering happen to be reported [29,30]. Despite the fact that syn.
