Journal ArticleDOI
Highly selective dispersion of single-walled carbon nanotubes using aromatic polymers.
TL;DR: A dramatic improvement in the preparation of single-walled carbon nanotubes solutions based on the ability of specific aromatic polymers to efficiently disperse certain nanotube species with a high degree of selectivity is reported.
Journal ArticleDOI
Polymer Structure and Solvent Effects on the Selective Dispersion of Single-Walled Carbon Nanotubes
Jeong-Yuan Hwang,Adrian Nish,James Doig,Sigrid Douven,Chun-Wei Chen,Li-Chyong Chen,Robin J. Nicholas +6 more
TL;DR: Combinations of different aromatic polymers and organic solvents have been studied as dispersing agents for preparing single-walled carbon nanotubes solutions, using optical absorbance, photoluminescence-excitation mapping, computer modeling, and electron microscopic imaging to characterize the solutions.
Journal ArticleDOI

TL;DR: In this paper, multi-wall carbon nanotubes (CNT) were coated with protonated polyaniline (PANI) in situ during the polymerization of aniline.
Journal ArticleDOI
Correlating defect density with carrier mobility in large-scaled graphene films: Raman spectral signatures for the estimation of defect density.
TL;DR: Both the connections of carrier mobility and the shift of neutrality points to a negative direction in relation to the defect density in graphene are observed for the first time in CVD-grown graphene films.
Journal ArticleDOI
Direct spectroscopic evidence of energy transfer from photo-excited semiconducting polymers to single-walled carbon nanotubes.
TL;DR: It has been found that energy is transferred to the carbon nanotubes when the polymer is photo-excited across its minimum energy gap, shown using photoluminescence excitation mapping in the range of both the polymer's and the nanotube's optical absorbance.
