Sharma R., Shetty K., Liang R., Chen C-J., Florida State University, US

Carbon nanotubes are emerging as potential tools in drug delivery nanocarriers to target specific cell types and carbon cages filled with metal molecules may improve MRI microimaging. The present paper reviews the current state of [...]

Conducting Polymer Nanocomposites: The Role of the Electronic Fingerprint of Carbon Nanotubes

Chiu P.L., Ma Y., Serrano A., Wang L., Mendelsohn R., He H., Rutgers University, US

In this presentation, we report that dispersion and functionalization of single-walled carbon nanotubes (SWNTs) with different dispersing methods and dispersing agents result different SWNTs with different electronic structures and surface chemistries. In-situ polymerization of the [...]

A latex-based concept for obtaining carbon nanotube-polymer nanocomposites

Grossiord N., Meuldijk J., Loos J., van der Schoot P., van Laake L.C., Regev O., Hart J., van der Schoot P., van Laake L.C., Miltner H.E., van der Schoot P., van Laake L.C., Koning C.E., Technical University of Eindhoven, NL

By using a latex-based technology, it is possible to efficiently disperse both single and multi wall carbon nanotubes (SWNTs and MWNTs) within most of the polymers that are produced by emulsion polymerization, or that can [...]

Closed form Exact Analytical Solutions for Effective Mechanical Properties and Responses for Nanotube Reinforced Nanocomposites

Askari D., Ghasemi-Nejhad M., University of Hawaii at Manoa, US

In this paper, analytical and numerical approaches are employed to investigate the effective axial mechanical properties and mechanical behavior of a three-phase composite cylindrical model, representing a unit cell for a polymer nanocomposite reinforced by [...]

Water Soluble Conducting Polymer Nanocomposite: Toward Electronic Understanding the Catalytic Role of ss-DNA Functionalized Single Walled Carbon Nanotubes

Ma Y., Chiu P.L., Ali S.R., Serrano A., Chen A., He H., Rutgers University, US

Single-stranded DNA functionalized single-walled carbon nanotubes (ss-DNA/SWNTs) act as catalytic molecular templates during oxidative polymerization of self-doped polyaniline. We found that not only was the polymerization rate greatly enhanced, but also the quality of the [...]
