Journal ArticleDOI
Thermal−Electrical Character of in Situ Synthesized Polyimide-Grafted Carbon Nanofiber Composites
Michael J. Arlen,David H. Wang,J. David Jacobs,Ryan S. Justice,Aaron Trionfi,Julia W. P. Hsu,Dale Schaffer,Loon-Seng Tan,Richard A. Vaia +8 more
TL;DR: In this article, two series of polymide (CP2)−carbon nanofiber (CNF) composites are prepared with quantitatively (smallangle X-ray scattering) comparable CNF dispersions, but differing in the structure of the CNF−polymer interface.
Journal ArticleDOI
Direct imaging of current paths in multiwalled carbon nanofiber polymer nanocomposites using conducting-tip atomic force microscopy
Aaron Trionfi,David Scrymgeour,Julia W. P. Hsu,M. J. Arlen,David Tomlin,J. D. Jacobs,David H. Wang,Loon-Seng Tan,Richard A. Vaia +8 more
TL;DR: In this paper, a conducting-tip atomic force microscopy (C-AFM) was used to study the spatial distribution of current paths and local electrical properties in carbon nanofiber/polymer nanocomposites.
Journal ArticleDOI
Direct measurement of the percolation probability in carbon nanofiber-polyimide nanocomposites.
TL;DR: The first experimental measurement of the geometric critical exponent beta associated with the percolation probability, the probability a metallic filler belongs to the conducting network, of an electrical composite is presented, likely belonging to the same universality class as the Bethe lattice.
Journal ArticleDOI
Electron Beam-Induced Damage of Alkanethiolate Self-Assembled Monolayers Adsorbed on GaAs (001): A Static SIMS Investigation†
TL;DR: In this article, the authors investigated the reaction pathways involved in electron-beam-induced damage of −CH3, −OH, and −COOH terminated alkanethiolate self-assembled monolayers (SAMs) adsorbed on GaAs (001) using time-of-flight secondary ion mass spectrometry.
Journal ArticleDOI
Comparison of chemical lithography using alkanethiolate self-assembled monolayers on GaAs (001) and Au.
TL;DR: It is demonstrated that well-defined multifunctional patterned surfaces can be produced on GaAs with only partial degradation of the SAM, allowing greatly reduced electron beam doses and UV irradiation times to be used.
