Pyrolytic carbon (PyC) was deposited on the surface of nanotubes using multiple cycles of chemical vapor infiltration. Morphological and structural characterization showed that when graphitization was done in one step, after the deposition of multiple cycles of PyC, the presence of a large amount of disordered carbon on the surface of nanotubes led to a poorly graphitized coating structure that did not resembled nanotube walls anymore. Graphitization of the AMWCNT/C sheets after each deposition cycle prevented the development of disordered carbon during the subsequent PyC deposition cycles. Using the cyclic-graphitization method, thick PyC coating layers were successfully graphitized into a crystalline structure that could not be differentiated from the original nanotube walls. TEM observation and X-ray data confirmed radial growth of nanotubes, while spectra collected from Raman spectroscopy revealed that radially grown CNTs had the same quality as graphitized pristine nanotubes. The focus of this study was to compare the effect of cyclic graphitization with a one-step graphitization method to gain insight on the necessary parameters needed to radially grow high quality CNTs.}, journal={CARBON}, author={Faraji, Shaghayegh and Yildiz, Ozkan and Rost, Christina and Stano, Kelly and Farahbakhsh, Nasim and Zhu, Yuntian and Bradford, Philip D.}, year={2017}, month={Jan}, pages={411–418} } @article{farahbakhsh_roodposhti_ayoub_venditti_jur_2015, title={Melt extrusion of polyethylene nanocomposites reinforced with nanofibrillated cellulose from cotton and wood sources}, volume={132}, ISSN={0021-8995}, url={http://dx.doi.org/10.1002/app.41857}, DOI={10.1002/app.41857}, abstractNote={Replacing petroleum-based materials with biodegradable materials that offer low environmental impact and safety risk is of increasing importance in sustainable materials processing. The objective of this study was to produce uniform nanofibrillated cot- ton from recycled waste cotton T-shirts using microgrinding techniques and compare its performance as reinforcing agent in thermo- plastic polymers constructs with wood-originated materials. The effect of the microgrinding process on morphology, crystallinity, and thermal stability of materials was evaluated by transmission electron microscopy (TEM), scanning electron microscope (SEM), X-ray diffraction (XRD), and thermogravimetry analysis (TGA). Nanofibrillated cotton resulted in higher crystallinity and thermal stability than fibrillated bleached and unbleached softwood. All the materials were extruded with low-density polyethylene to fabricate nano- composite films. Nanofibrillated cotton nanocomposites had a higher optical transparency than did the wood-based composites. The mechanical properties of the nanofibrillated cotton nanocomposites were largely improved and showed 62.5% increase in strength over the wood-based nanofibrillated containing composites, in agreement with the higher crystallinity of the nanosized cotton- derived filler material.
