A Composite from Poly(m-phenylenevinylene-co-2,5-dioctoxy-p-phenylenevinylene) and Carbon Nanotubes: A Novel Material for Molecular Optoelectronics

Noncovalent Nonspecific Functionalization and Solubilization of Multi‐Walled Carbon Nanotubes at High Concentrations with a Hyperbranched Polyethylene

“…[2,4,6] Noncovalent functionalization of carbon nanotubes with polymers generally involves noncovalent but specific sidewall adsorption or wrapping of specialty polymers which bear specifically designed functional groups capable of forming p-p stacking, van der Waals interactions, or static charge interactions with the conjugated aromatic nanotube sidewall. A few specialty polymers, including the most notable p-p interacting conjugated polymers [7][8][9][10][11][12][13][14][15] and pyrene-containing polymers, [16][17][18][19][20][21][22] poly(vinylpyrrolidone), [23] polystyrene sulfonate, [23] and block copolymers, [24][25][26] have been successfully developed for effective noncovalent and specific solubilization of carbon nanotubes. Synthesis of these specialty polymers, however, often requires the use of specially designed monomers and sophisticated polymerization techniques.…”

Modifying the Electronic Character of Single-Walled Carbon Nanotubes Through Anisotropic Polymer Interaction: A Raman Study

“…[6] We need a well-characterized processing mechanism to effectively separate metallic and semiconducting SWNTs from asgrown mixtures for individual applications. The poly(methyl methacrylate) (PMMA) matrix used in this study belongs to a class of materials that has good structural stability and flexible processability but is electronically insulating.…”

Polymer Composites of Carbon Nanotubes Aligned by a Magnetic Field

“…[1] Actually, it has been shown experimentally that the introduction of nanotubes into a polymer matrix improves the electrical conductivity [2] as well as the mechanical properties [3±5] of the original polymer matrix. Moreover, carbon nanotubes have been suggested to increase the efficiency of polymer-based optical devices, such as polymer light-emitting diodes [6] and photodiodes. [7,8] Because of a unique one-dimensional structure of nanotubes, a high anisotropy is expected for nanotube±polymer composites when nanotubes are aligned in a certain direction.…”
