Journal ArticleDOI
Hydrothermal synthesis and pseudocapacitance properties of MnO2 nanostructures.
TL;DR: Interestingly, SEM, TEM, and HRTEM revealed a variety of structures ranging from nanostructured surface with a distinct platelike morphology to nanorod depending upon the hydrothermal reaction time employed during the preparation of the manganese oxide: increasing the amount of individual nanorods in the materials prepared with longer hydrother mal reaction time.
Journal ArticleDOI
Single-step in situ synthesis of polymer-grafted single-wall nanotube composites.
Gunaranjan Viswanathan,Nirupama Chakrapani,Hoichang Yang,Bingqing Wei,Hyunsoo Chung,Kilwon Cho,Chang Y. Ryu,Pulickel M. Ajayan +7 more
TL;DR: An in situ composite synthesis technique has been developed by grafting polystyrene chains onto single-wall carbon nanotubes (SWNTs) via a single-step debundling/polymerization scheme that eliminates the need for nanotube pretreatment prior to functionalization and allows attachment of polymer molecules to pristine tubes without altering their original structure.
Journal ArticleDOI
Aligned carbon nanotube-polymer hybrid architectures for diverse flexible electronic applications.
Yung Joon Jung,Swastik Kar,Saikat Talapatra,Caterina Soldano,Gunaranjan Viswanathan,Xuesong Li,Zhaoling Yao,Fung Suong Ou,Aditya Avadhanula,R. Vajtai,Seamus A. Curran,Omkaram Nalamasu,Pulickel M. Ajayan +12 more
TL;DR: The fabrication and electrical characterization of a flexible hybrid composite structure using aligned multiwall carbon nanotube arrays in a poly(dimethylsiloxane) (PDMS) matrix is presented, giving rise to extremely flexible conducting structures with unique electromechanical properties.
Journal ArticleDOI
Temperature dependence of radial breathing mode Raman frequency of single-walled carbon nanotubes
Nachiket R. Raravikar,Pawel Keblinski,Apparao M. Rao,Mildred S. Dresselhaus,Linda S. Schadler,Pulickel M. Ajayan +5 more
TL;DR: In this article, the authors estimate the contributions from three factors that may be responsible for the observed temperature dependence of the radial breathing mode frequency, including thermal expansion of individual SWNTs in the radial direction, softening of the C-C (intratubular) bonds, and softens of the van der Waals intertubular interactions in SWNT bundles.
Journal ArticleDOI
Synthesis and Characterization of Thickness-Aligned Carbon Nanotube−Polymer Composite Films
Nachiket R. Raravikar,Linda S. Schadler,Aravind Vijayaraghavan,Yiping Zhao,Bingqing Wei,Pulickel M. Ajayan +5 more
TL;DR: In this paper, a pre-aligned multi-wall carbon nanotube arrays were infiltrated with methyl methacrylate (MMA) and the MMA was polymerized, and the resulting composite films have well-dispersed, aligned nanotubes.
