Temperature-induced nucleation of poly(p-phenylenevinylene-co-2,5-dioctyloxy-m-phenylene vinylene) crystallization by HiPco single-walled carbon nanotubes

Article Abstract:

Hybrid systems of the conjugated organic polymer poly(p-phenylene vinylene-co-2,5-dioctyloxy-m-phenylene vinylene) (PmPV) and HiPco single-walled carbon nanotubes are explored using spectroscopic and thermal techniques to determine specific interactions. The results revealed that the optimum polymer-tube interaction does not occur at ambient temperature.

Formation of covalently linked self-assembled films of a functional hyperbranched conjugated poly(phenylene vinylene)

Article Abstract:

A new self-assembled method using a covalent bond as the linkage between the hydrophilic substrate and a functional hyperbranched molecule poly(phenylene vinylene) (SPPV) is used to form ordered homogenous films. The difference of fluorescence properties between the SPPV SA film and spincoating film indicate that the SA film is ordered and homogeneous.

Brownian dynamics simulation of hyperbranched polymers under elongational flow

Article Abstract:

Brownian dynamics simulations of trifunctional hyperbranched polymers (HP) of different molecular weight (N), degree of branching (DB), and Weiner index (W) have been performed under the influence of uniaxial elongational flow. The HP and dendrimer average extension and orientation are calculated as a function of epsilon.
