Ž . Several polymer-coated and polymer-grafted multi-walled carbon nanotubes MWNTs were synthesized and characterized using TEM and HRTEM. The polymer-coated or polymer-grafted MWNTs formed stable solutions in DMF. Their nonlinear optical properties were investigated using 532 nm nanosecond laser pulses. These polymer–MWNT composites still possess strong nonlinear optical properties. q 2000 Els...
High-permeance, molecular-sieving, nanoporous single-layer graphene (NSLG) membranes are highly promising for gas separation. However, the formation of cracks during transfer NSLG to a low-cost porous support is difficult avoid. These detrimental selectivity, and therefore, make scale-up gas-sieving challenging. To mitigate crack on macroporous supports, herein, we demonstrate mechanical reinfo...
Multiwalled carbon nanotubes (MWNTs), with their excellent properties, have long been considered as a model material for realizing the potential of nanotechnology. Several techniques have been developed to tailor and manipulate MWNTs, and they have shown promise in the construction of nanobalances, nanosensors, SPM probes, nanoelectronics, fuel cells, and so on. In order to achieve their full c...
We report a fully integrated, portable, battery-operated electronic nose system comprising a bio-inspired two-layer multiple-walled carbon nanotube (MWNT)-polymer composite sensor array, a bio-inspired fast-adaptive readout circuit, and a microprocessor embedded with a pattern recognition algorithm. The two-layer MWNT-polymer composite sensor is simple to operate, and the membrane quality can b...
The effects of processing conditions and apparent nanotube length on properties are investigated for carbon nanotube yarns obtained by solid-state drawing of an aerogel from a forest of multi-walled carbon nanotubes. Investigation of twist, false twist, liquid densification and combination methods for converting the drawn aerogel into dense yarn show that permanent twist is not needed for obtai...
A novel Si-MWNT nanocomposite synthesized via a CVD process shows a high reversible capacity of over 1500 mAh g(-1) and stable cycling performance, which can be ascribed to the maintenance of a good conductive network by means of the direct scattered growth and pinning of MWNTs on Si particles.
