In this work, vertically aligned carbon nanotubes (VACNTs) grown on aluminum foils were used as flexible supercapacitor electrodes. Aluminum foils were used as readily available, cheap and conductive substrates, and VACNTs were grown directly on these foils through chemical vapor deposition (CVD) method. Solution based ultrasonic spray pyrolysis (USP) method was used for the deposition of the CNT catalyst. Direct growth of VACNTs on aluminum foils ruled out both the internal resistance of the supercapacitor electrodes and the charge transfer resistance between the electrode and electrolyte. A specific capacitance of 2.61 mF/cm(2) at a scan rate of 800 mV/s was obtained from the fabricated electrodes, which is further improved through the bending cycles.

Vibration damping behavior of epoxy matrix composites reinforced with carbon fibers and carbon nanotubes Avil, Esma; Kaynak, Cevdet; Department of Metallurgical and Materials Engineering (2019) The main objective of this study was to investigate contribution of the nonfunctionalized multi-walled carbon nanotubes (CNT) on the vibration damping behavior of first neat epoxy resin and then unidirectional and bidirectional continuous carbon fiber (CF) reinforced epoxy matrix composites. Epoxy/CNT nano-composites were produced by ultrasonic solution mixing method, while the continuous CF reinforced composite laminates were obtained via resin-infusion technique. Vibration analysis data of the specimens w...
Structural Vibration Analysis of Single Walled Carbon Nanotubes with Atom Vacancies Dogan, Ibrahim Onur; Yazıcıoğlu, Yiğit (2014-11-01) Recent investigations in nanotechnology show that carbon nanotubes have significant mechanical, electrical and optical properties. Interactions between those are also promising in both research and industrial fields. Those unique characteristics are mainly due to the atomistic structure of carbon nanotubes. In this paper, the structural effects of vacant atoms on single walled carbon nanotubes are investigated using matrix stiffness method. In order to use this technique, a linkage between structural mechan...
Mechanical, electrical and thermal properties of carbon fiber reinforced poly(dimethylsiloxane)/polypyrrole composites Cakmak, G; Kucukyavuz, Z; Kucukyavuz, S; Cakmak, H (2004-01-01) Conductive and flexible carbon fiber (CF) reinforced polydimethylsiloxane (PDMS)/polypyrrole (PPy) composites were synthesized electrochemically. Electrochemical synthesis was performed at + 1.1 V using p-toluenesulfonic acid as supporting electrolyte and water as solvent. Composites were characterized by thermal gravimetric analysis, scanning electron microscopy (SEM), conductivity measurements and mechanical tests. Conductivities of composites were observed in the range of 2.2-4 S/cm. SEM studies show tha...
Experimental investigation of the effect of CNT addition on the strength of CFRP curved composite beams Arca, M.A.; Uyar, I.; Çöker, Demirkan (2015-01-01) Carbon nanotubes (CNT) have been attracting attention as a toughening material in composite matrix due to their excellent mechanical properties. However, superior properties of CNTs have not yet been realized in the strengthening of composites against fracture. This study focuses on investigating the effect of CNT variation in the epoxy resin on the strength of curved composite beams. Specimens are [0/90] fabric carbon/epoxy composite laminates manufactured by hand layup technique 3 % wt CNT fractions in th...
Nanomaterial-Enhanced All-Solid Flexible Zinc-Carbon Batteries Hiralal, Pritesh; Imaizumi, Shinji; Ünalan, Hüsnü Emrah; Matsumoto, Hidetoshi; Minagawa, Mie; Rouvala, Markku; Tanioka, Akihiko; Amaratunga, Gehan A. J. (2010-05-01) Solid-state and flexible zinc carbon (or Leclanche) batteries are fabricated using a combination of functional nanostructured materials for optimum performance. Flexible carbon nanofiber mats obtained by electrospinning are used as a current collector and cathode support for the batteries. The cathode layer consists of manganese oxide particles combined with single-walled carbon nanotubes for improved conductivity. A polyethylene oxide layer containing titanium oxide nanoparticles forms the electrolyte laye...
