Multiwalled carbon nanotubes with chemically grafted polyetherimides.
Covalent attachment of a non-fluorinated polyetherimide onto the surface of carboxylic acid-functionalized multiwalled carbon nanotubes (MWNTs) has been achieved via grafting reactions. This confirms for the first time that the grafting reaction occurs at the nanotube surface when the carboxylic acid-functionalized MWNTs react with the polyetherimide with amine-terminated groups, through both a...
متن کاملMultiwalled Carbon Nanotubes: Environmental Application
The high external surface area leads to a significant increase in the surface contact between the gaseous or liquid reactants and the active phase supported on this nanostructured host which is a prerequisite for its use as catalyst support, especially in liquid phase medium where diffusion rate is predominant [2]. Also, the strong interactions between the exposed prismatic planes and the depos...
متن کاملEnhancing the photostability of poly(3-hexylthiophene) by preparing composites with multiwalled carbon nanotubes.
Poly(3-hexylthiophene) (P3HT) degrades in organic solvents containing dissolved molecular oxygen when irradiated with ultraviolet light. Hence, it is important to develop strategies that can enhance the photostability of P3HT and enhance the device performance. In this work, we report that preparing composites of P3HT with appropriate amounts of multiwalled carbon nanotube (MWCNT) results in su...
متن کاملCharacterization of Multiwalled Carbon Nanotube-Reinforced Hydroxyapatite Composites Consolidated by Spark Plasma Sintering
Pure HA and 1, 3, 5, and 10 vol% multiwalled carbon nanotube- (MWNT-) reinforced hydroxyapatite (HA) were consolidated using a spark plasma sintering (SPS) technique. The relative density of pure HA increased with increasing sintering temperature, but that of the MWNT/HA composite reached almost full density at 900°C, and then decreased with further increases in sintering temperature. The relat...
متن کاملLithiation-induced embrittlement of multiwalled carbon nanotubes.
Lithiation of individual multiwalled carbon nanotubes (MWCNTs) was conducted in situ inside a transmission electron microscope. Upon lithiation, the intertube spacing increased from 3.4 to 3.6 Å, corresponding to about 5.9% radial and circumferential expansions and ∼50 GPa tensile hoop stress on the outermost tube wall. The straight tube walls became distorted after lithiation. In situ compress...
