“…These materials can be produced through the heat treatment (pyrolysis) of aligned nanofiber polymer matrix nanocomposite (A-PNC) precursors, which are analogous to the APNCs reported elsewhere [15][16][17][18][19][20][21][22][23][24] . Such processing follows the typical synthesis routes of polymer derived ceramics [25][26][27][28] , but relies on capillary [15][16][17][18][19][20][21] or vacuum [21][22][23][24] assisted wetting of the aligned nanofibers rather than surfactant or functionalization assisted mixing. In order to manufacture aligned nanofiber carbon matrix nanocomposites (A-CMNCs) with tailored properties, the porosity of the matrix, which strongly influences its material properties, must be controlled.…”

Intrinsic and scale-dependent properties of carbon nanotubes (CNTs) have led aligned CNT architectures to emerge as promising candidates for next-generation multifunctional applications. Enhanced operating regimes motivate the study of CNT-based aligned nanofiber carbon matrix nanocomposites (CNT A-CMNCs). However, in order to tailor the material properties of CNT A-CMNCs, porosity control of the carbon matrix is required. Such control is usually achieved via multiple liquid precursor infusions and pyrolyzations. Here we report a model that allows the quantitative prediction of the CNT A-CMNC density and matrix porosity as a function of number of processing steps. The experimental results indicate that the matrix porosity of A-CMNCs comprised of ∼ 1% aligned CNTs decreased from ∼ 61% to ∼ 55% after a second polymer infusion and pyrolyzation. The model predicts that diminishing returns for porosity reduction will occur after 4 processing steps (matrix porosity of ∼ 51%), and that > 10 processing steps are required for matrix porosity < 50%. Using this model, prediction of the processing necessary for the fabrication of liquid precursor derived A-CMNC architectures, with possible application to other nanowire/nanofiber systems, is enabled for a variety of high value applications.

“…In particular, SWCNTs are promising as filler materials in polymer-based composites due to their ability to enhance the performance of matrices. It has been demonstrated that incorporation of SWCNTs into polymers enhances mechanical [5], electrical [6], and thermal properties [7], and therefore, SWCNT/polymer composites have opened up new device applications such as actuators [8,9], sensors [10], and photonic devices [11].…”

AbstractWe present a method to develop single-wall carbon nanotube (SWCNT)/polymer composites into arbitrary three-dimensional micro/nano structures. Our approach, based on two-photon polymerization lithography, allows one to fabricate three-dimensional SWCNT/polymer composites with a minimum spatial resolution of a few hundreds nm. A near-infrared femtosecond pulsed laser beam was focused onto a SWCNT-dispersed photo resin, and the laser light solidified a nanometric volume of the resin. The focus spot was three-dimensionally scanned, resulting in the fabrication of arbitrary shapes of SWCNT/polymer composites.SWCNTs were uniformly distributed throughout the whole structures, even in a few hundreds nm thick nanowires. Furthermore, we also found an intriguing phenomenon that SWCNTs were self-aligned in polymer nanostructures, promising improvements in mechanical and electrical properties. Our method has great potential to open up a wide range of applications such as micro-and nanoelectromechanical systems, micro/nano actuators, sensors, and photonics devices based on CNTs. Main Text

“…With the great progress achieved in this field, CNTs have been used to synthesize not only various polymer/CNTs composites [4][5][6][7][8] but also various CNTs/metal oxide hybrids [9][10][11][12][13], where CNTs can serve as high-performance supporting materials. The decoration of CNTs with metal oxide nanoparticles can give them new properties and potentials for various applications [14][15][16][17][18].…”

In this paper, a facile synthesis process is proposed to prepare multi-walled carbon nanotubes/magnetite (MWCNTs/Fe 3 O 4 ) hybrids. The process involves two steps: 1) water-soluble CNTs are synthesized by one-pot modification using potassium persulfate (KPS) as oxidant. 2) Fe 3 O 4 is assembled along the treated CNTs by employing a facile hydrothermal process with the presence of hydrazine hydrate as the mineralizer. The treated CNTs can be easily dispersed in aqueous solvent. Moreover, X-ray photoelectron spectroscopy (XPS) analysis reveals that several functional groups such as potassium carboxylate (-COOK), carbonyl (-C=O) and hydroxyl (-C-OH) groups are formed on the nanotube surfaces. The MWCNTs/Fe 3 O 4 hybrids are characterized with respect to crystal structure, morphology, element composition and magnetic property by x-ray diffraction (XRD), transmission electron microscopy (TEM), XPS and superconducting quantum interference device (SQUID) magnetometer. XRD and TEM results show that the Fe 3 O 4 nanoparticles with diameter in the range of 20-60 nm were firmly assembled on the nanotube surface. The magnetic property investigation indicated that the CNTs/Fe 3 O 4 hybrids exhibit a ferromagnetic behavior and possess a saturation magnetization of 32.2 emu/g. Further investigation indicates that the size of assembled Fe 3 O 4 nanoparticles can be turned by varying experiment factors. Moreover, a probable growth mechanism for the preparation of CNTs/Fe 3 O 4 hybrids was discussed.
