In this paper, carbon nanotubes (CNTs) were added into chitosan (CS) hydrogels in the form of chitosan modified CNTs (CS-CNTs) composites to prepare carbon nanotubes hydrogels (CNTs-GEL). The products, named CS-MWCNTs, were characterized by scanning electron microscope (SEM) and Fourier transform infrared (FTIR) spectroscopy. Swelling properties and effect of pH on controlled release performanc...

Electrophoretic process was applied to the deposition of carbon nanotubes on the surface of carbon fabrics in order to enhance the properties of CNT/carbon fabric hybrid composites. Carbon fabrics were modified by two methods: Cu deposition by cathodic method and Cu coating by thermal vaporization method. CNTs were modified by PEI and oxidation treatment. The effects of carbon fabric and CNTs m...

The growth behavior and enhanced field emission properties of multiwalled carbon nanotubes were investigated using Ti as an underlayer and over layer. Ti of 10 nm thickness was deposited underneath Fe catalyst and their interaction behavior was observed for growth of carbon nanotubes. It was observed that underlayer deposition of Ti improves the growth of CNTs by acting as a barrier. In the oth...

The functionalization of multi-walled carbon nanotubes (MW-CNTs) was obtained by generating reactive perfluoropolyether (PFPE) radicals that can covalently bond to MW-CNTs' surface. Branched and linear PFPE peroxides with equivalent molecular weights of 1275 and 1200 amu, respectively, have been thermally decomposed for the production of PFPE radicals. The functionalization with PFPE chains has...

Carbon nanotube (CNT) nanoporous membranes based on pre-aligned CNTs have superior nano-transportation properties in biological science. Herein, we report a smart temperature- and temperature-magnetic-responsive CNT nanoporous membrane (CNM) by grafting thermal-sensitive poly(N-isopropylacrylamide) (PNIPAM) and Fe3O4 nanoparticles (Fe3O4-NPs) on the open ends of pre-aligned CNTs with a diameter...

Graphene nanoribbons (GNR) are one of the most promising candidates for the fabrication of graphene-based nanoelectronic devices such as high mobility field effect transistors (FET). Here, we report a high-yield fabrication of a high quality another type of GNR analogue, fully flattened carbon nanotubes (flattened CNTs), using solution-phase extraction of inner tubes from large-diameter multi-w...

Since their discovery, carbon nanotubes and carbon nanofibers (CNTs or CNFs) have exhibited potential in a wide range of physical and chemical applications [1] and [2]. For applications in gas phase catalysis, loose CNTs or CNFs are unsuited because they limit the catalyst–reactant transport properties and they are difficult to handle when filling in the reactor tubes. In addition, there is a h...

Lithium-sulfur (Li-S) batteries have become promising candidates for electrical energy storage systems due to their high theoretical specific energy density, low cost and environmental friendliness. However, there are some technical obstacles of lithium-sulfur batteries to be addressed, such as the shuttle effect of polysulfides. Here, we introduced organically modified carbon nanotubes (CNTs) ...
