Improvement on wettability between carbon nanotubes and Sn

Abstract

Several metals (Sn, Cu and Ag) were coated on the surface of carbon nanotubes (CNTs) by electroless plating to improve the wettability between CNTs and the Sn matrix. The coated CNTs were characterised by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). The results reveal that the metals are decorated effectively on the sidewalls of CNTs. The deposited metals are supposed to serve as the medium for interacting with the melted Sn matrix and achieve high strength interfacial adhesion. It was found that the Ag coated CNTs are wetted to a certain degree by melted Sn and embedded well in the matrix. While in the case of Sn and Cu coated CNTs, fewer CNTs are embedded in the Sn matrix because of desorption or oxidation.

Structural Engineering of SnS2Encapsulated in Carbon Nanoboxes for High‐Performance Sodium/Potassium‐Ion Batteries Anodes

“…The core of the yolk–shell structure tends to be spherical owing to the surface tension of the liquid Sn (Figure 2c,e). [ 44,45 ] After sulfurization, the core presents a degree of growth (Figure 2d,f), which is ascribed to the formation of SnS 2 (Sn + 2S → SnS 2 ). The designed void space is capable of accommodating the volume change and aggregation of SnS 2 nanoparticles during charge/discharge, consequently preventing the pulverization of the electrode and thereby benefiting the cycling stability.…”

Al–CNT–Ni composite with significantly increased strength and hardness

“…CNTs were first purified to get rid of impurities such as amorphous carbon, metal catalyst and smaller fullerenes by ultrasonically dispersing in an aqueous solution of HNO 3 (70%) at 80 C for 2 h [16,17]. HNO 3 treatment also modifies surface properties to get better dispersion in the electrolyte with high-density activation sites for subsequent reactions [18]. After acid treatment CNTs become hydrophilic to adsorb metallic particles easily onto CNT's surface [18][19][20].…”

Ethylene Methacrylic Acid (EMAA) Single Splat Morphology

“…The surface condition [7][8][9][10] and the wettability of the substrate play an important role in the morphology of splats [11]. There are three factors affecting the wettability of the substrate.…”
