“…The thermal properties of CNTs are also influenced by the functionalization [52]. The thermal conductivity of the polymer can be easily modified by incorporating CNTs in their matrix, and this potential is widely affected by the nature of CNTs [36,37,53].…”

Carbon nanotubes (CNTs) are considered a promising nanomaterial for diverse applications owing to their attractive physicochemical properties such as high surface area, superior mechanical and thermal strength, electrochemical activity, and so on. Different techniques like arc discharge, laser vaporization, chemical vapor deposition (CVD), and vapor phase growth are explored for the synthesis of CNTs. Each technique has advantages and disadvantages. The physicochemical properties of the synthesized CNTs are profoundly affected by the techniques used in the synthesis process. Here, we briefly described the standard methods applied in the synthesis of CNTs and their use in the agricultural and biotechnological fields. Notably, better seed germination or plant growth was noted in the presence of CNTs than the control. However, the exact mechanism of action is still unclear. Significant improvements in the electrochemical performances have been observed in CNTs-doped electrodes than those of pure. CNTs or their derivatives are also utilized in wastewater treatment. The high surface area and the presence of different functional groups in the functionalized CNTs facilitate the better adsorption of toxic metal ions or other chemical moieties. CNTs or their derivatives can be applied for the storage of hydrogen as an energy source. It has been observed that the temperature widely influences the hydrogen storage ability of CNTs. This review paper highlighted some recent development on electrochemical platforms over single-walled CNTs (SWCNTs), multi-walled CNTs (MWCNTs), and nanocomposites as a promising biomaterial in the field of agriculture and biotechnology. It is possible to tune the properties of carbon-based nanomaterials by functionalization of their structure to use as an engineering toolkit for different applications, including agricultural and biotechnological fields.

“…Structurally, particles and reinforcing fibers or layers are enhancing the strength in the matrix of the composite. Most generally, nano-composites can be classified based on the matrix material as: the polymer matrix nano-composites [29,30], nano-composites with ceramic matrix [31,32], and metal matrix nano-composites [3,33]. This study is focused on the metal matrix nano-composite (MMNC).…”

a b s t r a c tIn this work, 2 vol% carbon nanotubes (CNTs) reinforced aluminum (Al) matrix composites of superior microstructural homogeneity are successfully synthesized using Bc equal-channel angular extrusion (ECAP) route. The key step in arriving at high level of homogeneous distribution of CNTs within Al was preparation of the powder using simultaneous attrition milling and ultra-sonication processes. Microstructure as revealed by electron microscopy and absence of Vickers hardness gradients across the material demonstrate that the material reached the homogeneous state in terms of CNT distribution, porosity distribution, and grain structure after eight ECAP passes. To facilitate comparison of microstructure and hardness, samples of Al were processed under the same ECAP conditions. Significantly, the composite containing only 2 vol% exhibits 20% increase in hardness relative to the Al samples.

“…Many polymer nanocomposites consist of polymers and thermally conductive nanomaterial were reported to obtain polymers with high thermal conductivity [10][11][12]. The commonly used nanomaterial include carbon(carbon nanotubes [13], carbon nanofibers [14], graphene [15], etc. ), oxides (aluminum oxide (Al 2 O 3 ) [16], beryllium (BeO) [17], (titanium oxide(TiO 2 ) [18], etc.…”

Epoxy is widely used in mechanical and electronic industries due to its excellent adhesive properties and mechanical performances. However, the poor thermal conductivity limits its application, especially in high density equipment. In order to improve the thermal conductivity of epoxy, silver nanoparticles decorated boron nitride nano-sheets (Ag-BN) were prepared and incorporated into the epoxy matrix to obtain nanocomposites (EP-AB) in this work. The EP-AB behaves a significant enhancement of 1089% at an Ag-BN loading of 25 vol% compared to the pure epoxy. The thermogravimetric curve shows that the thermal stability of nanocomposites is improved with the addition of Ag-BN. Moreover, dynamic thermomechanical analysis reveals that Ag-BN can effectively reduce the segmental mobility of the epoxy matrix, which helps to improve the stiffness, decrease the mechanical loss, and increase the glass transition temperature of EP-AB. Those three properties gain an optimum value when the content of Ag-BN is 20 vol%. Also, the nanocomposites perform more stability in mechanical properties than pure epoxy under a varied frequency. The Cole-Cole plot of storage modulus and loss modulus shows that the pure epoxy and nanocomposites with low nanomaterial content are homogenous and the uniformity begins to decrease when the addition of Ag-BN is 20 vol%.
