Electrically Conducting Polymers As Templating Interfaces for Fabrication of Copper Nanotubes

Abstract

Submicrometer tubes have been fabricated by a polymer-based template approach using electroless deposition. The copper was deposited on polystyrene fibers functionalized with an interfacial electrically conducting polyaniline thin film layer. Thermal degradation of the functionalized fiber templates resulted in copper tubes of diameter 1600 ± 50 nm with wall thicknesses ranging between 100 and 200 nm. The morphology and elemental analysis of copper coaxial fibers was analyzed using SEM and EDS. Electrical properties were analyzed using FTIR and PXRD was used to study crystal structure of copper nanotubes.

Hierarchically micro/nanostructured porous metallic copper: Convenient growth and superhydrophilic and catalytic performance

“…Copper (Cu) nanoparticles are progressively attractive for catalysis because their large surface area-to-volume ratio guarantees effective utilization of expensive metals. [6][7][8][9] Up to now, various methods have been developed to prepare Cu nanocrystals with different morphologies, such as nanocubes, 10,11 nanowires, [12][13][14] nanorods, 15 cigar-shaped nanocrystals, 16 nanodisks, 17 dendritic nanostructures, 18 pentagonal bipyramids, 19 and hollow structures. 20,21 Even though such progress has been made toward determining the complex structures of Cu as well as establishing structure-function relationships for them, to the best of our knowledge, little work has been done with a focus on Cu crystals with porous superstructures.…”

Nanowires sheathed inside nanotubes: Manipulation, properties and applications

“…During the last decade, a variety of inorganic solids with layered (besides carbon) or non-layered crystal lattices have been found to form a tubular structure. Nowadays, the reported inorganic nanotubes have included many families such as transition metal chalcogenides [2][3][4][5][6][7][8], transition metal and rare earth oxides [3,5,[9][10][11][12][13][14], transition metal halogenous [15], elemental metals [16][17][18][19], boron-and silicon-based materials [20][21][22][23][24][25][26][27], and so on, they showed unique electronic, optical, mechanical and chemical properties and offered a great potential for various applications [28][29][30]. A most promising nanotube application relies on the characteristic internal hollow cavity peculiar to a tubular shape, implying some intriguing capillarity and wetting phenomena and inter-core chemistry [31][32][33][34][35].…”

Polydopamine Modified Activated Carbon for Capacitive Desalination

“…8 The electrode material with characteristics such as high surface area, suitable pore-size distribution, high conductivity and good wettability are essential requirements for desalination in CDI process. 9 A variety of carbon materials, such as carbon aerogel, [10][11][12] carbon nanotube, 13,14 carbon nanofibers, [15][16][17][18] mesoporous carbon 19,20 graphene [21][22][23] and activated carbon (AC) 24,25 are currently applied to fabricate the CDI electrodes. Amongst all of them, AC is one of the most widely used, due to its abundant porosity, large surface area, low cost and high commercial availability.…”
