Thin film composite (TFC) nanofiltration (NF) membranes supported by polymeric have suffered from limited mechanical properties and chemical cleaning stability, resulting in an increasing operation cost. Strengthening the support of TFC is expected to provide great stability for membranes. This work provided a membrane constructed on poly (vinyl alcohol) (PVA) incorporated carbon nanotube film,...

Spatial dispersion effect of aligned carbon nanotubes (CNTs) in the terahertz (THz) region has significance for both theoretical and applied consideration due to the unique intrinsically anisotropic physical properties of CNTs. Herein, we report the angular dependent reflection of p-polarized THz wave from vertically aligned multi-walled CNT arrays in both experiment and theory. The spectra ind...

The carbon nanotube (CNT) field emitter was fabricated using a thin free-standing CNT film, indicating line-shape emitter. Field emission properties of the were investigated in both diode and triode configurations. showed low turn-on electric 1.8 V/μm high current 40.3 mA, corresponding to density 96 A/cm configuration. It also exhibited anode 40 95.2 In addition, good electron beam tra...

Conditions for the transfer printing of patterned carbon nanotube (CNT) films, along with a Au-gate, a poly methylmethacrylate (PMMA) dielectric layer and Au source-drain electrodes have been developed for the fabrication of thin-film transistors on a polyethylene terephthalate (PET) substrate. Chemical vapor deposition (CVD) grown CNTs were patterned using a photolithographic method. Transfer ...

Thermophones for over a century have been thought to function as thermo-acoustic devices converting an alternating current to rapid temperature changes in thin platinum films. Subsequent pressure changes in the surrounding air allow the sound to propagate. Recently, thermophones from nanoscale sheets of carbon nanotubes (CNTs) are claimed to have far lower specific heat than platinum, and there...

We report an industrially scalable, fast, and simple process for the large scale fabrication of optically transparent and electrically conducting thin films of single-walled carbon nanotubes (SWNT). Purified, pristine HiPco SWNTs were dispersed in water at high concentrations with the help of surfactants, rod-coated into uniform thin films, and doped by various acids. We show how to combine dif...

Today the rapid growth of fiber-reinforced polymer (FRP) applications in the automotive and aerospace industry has motivated many researches to perform life-cycle analyses of FRP structures. While its strength-to-weight ratio outperforms conventional metals, FRP is inherently heterogeneous and experiences complex failure modes, thus making them challenging for structural analysis and design. As...

Thin-walled, open-ended, and well-aligned N-doped carbon nanotubes (CNTs) on the quartz slides were synthesized by using acetonitrile as carbon sources. As-obtained products possess large thin-walled index (TWI, defined as the ratio of inner diameter and wall thickness of a CNT). The effect of temperature on the growth of CNTs using acetonitrile as the carbon source was also investigated. It is...

Carbon nanotube (CNT) film electrodes were fabricated by a novel process involving the electrostatic spray deposition (ESD) of a CNT solution. Acid treated CNTs were dispersed in an aqueous solvent through sonication and then the CNT solution was electrostatically sprayed onto a metallic substrate by the ESD method. The CNT film electrodes showed well-entangled and interconnected porous structu...

Carbon nanotube (CNT) films were grown by microwave plasma-enhanced chemical vapor deposition process on four types of Si substrates: (i) mirror polished, (ii) catalyst patterned, (iii) mechanically polished having pits of varying size and shape, and (iv) electrochemically etched. Iron thin film was used as catalytic material and acetylene and ammonia as the precursors. Morphological and struct...
