Atomistic modeling of solubilization of carbon nanotubes by non-covalent functionalization with poly(p-phenylenevinylene- co-2,5-dioctoxy-m-phenylenevinylene)

Langmuir-blodgett assembly of densely aligned single-walled carbon nanotubes from bulk materials.

FOR WEB PUBLICATION. Single-walled carbon nanotubes (SWNTs) exhibit advanced electrical and surface properties useful for high performancenanoelectronics. Important to future manufacturing of nanotube circuits is large-scale assembly of SWNTs into aligned forms.Despite progress in assembly and oriented synthesis, pristine SWNTs in aligned and close-packed form remain elusive andneed...

Hole blocking in carbon nanotube–polymer composite organic light-emitting diodes based on poly (m-phenylene vinylene-co-2, 5-dioctoxy-p-phenylene vinylene)

Investigation of the interfacial binding between single-walled carbon nanotubes and heterocyclic conjugated polymers.

Molecular dynamics (MD) simulations were performed to investigate the interfacial binding between the single-walled carbon nanotubes (SWCNTs) and conjugated polymers including polythiophene (PT), polypyrrole (PP), poly(2,6-pyridinylenevinylene-co-2,5-dioctyloxy-p-phenylenevinylene) (PPyPV), and poly(m-phenylenevinylene-co-2,5-dioctyloxy-p-phenylenevinylene) (PmPV). The intermolecular interactio...

Molecular dynamics simulations of the elastic properties of polymer/carbon nanotube composites

Carbon nanotubes (CNTs) are promising additives to polymeric materials due to the potential for their enhancement of the structural, mechanical and electronic properties of the resulting composite. However, improvements in properties are by no means guaranteed, and the results are often sensitive to the particular polymer chosen, in addition to the quantity and quality of CNTs used in the compo...

Experimental observation of scaling laws for alternating current and direct current conductivity in polymer-carbon nanotube composite thin films

Alternating current ~ac! and direct current ~dc! conductivities have been measured in polymer-nanotube composite thin films. This was carried out for a range of concentrations of multiwall nanotubes in two polymer hosts, poly~m-phenylenevinylene-co-2,5-dioctyloxyp-phenylenevinylene! ~PmPV! and polyvinylalcohol ~PVA!. In all cases the dc conductivity sDC was ohmic in the voltage range studied. I...
