Two-dimensional lattice Monte Carlo simulation of the compatibility of A/B/functionalized A ternary polymer mixtures coupled with chemical reaction
Compatibility of A/B and functionalized A ternary polymer mixtures was studied by Monte Carlo simulation in a two-dimensional lattice. Polymer A was a nonreactive polymer, whereas polymer B was a reactive polymer and immiscible with polymer A. Functionalized polymer A could react with the end group of polymer B, leading to the formation of block copolymers. Simulation results showed the phase do...

How Well Can One Separate Copolymers According to Both Chemical Compositions and Sequence Distributions?
Partitioning of statistical AB type copolymer chains into a slit pore was studied with Monte Carlo simulations on a simple cubic lattice with self-avoiding walk models. Only one of the monomer types, B monomers, has attractive interaction with the surface, while the A monomers have no interaction with the surface. The critical adsorption point (CAP) of the copolymer at a given chemical compositi...

Preparation of Fluorescent Conjugated Polymer Films with Different Emission Colors: Investigation into the Influences of Chemical Structure and Morphology
A series of PPV fi lms with different fl uorescent emission colors are prepared using a facile approach. Modifi ed from the conventional Wessling route, the labile sulfonium groups in the polymer precursor (pre-PPV) are partly substituted to various degrees by relatively stable methoxy groups, followed by a regular thermal elimination step to obtain PPV. Different chemical structures among these...

Well-de?ned polypyrrole nano?akes via chemical oxidative polymerization in the presence of sodium alkane sulfonate
The conductive polymers with unique nanostructures have attracted intense interest due to their potential
application. Here the well-de?ned polypyrrole nano?akes (PPy/AS) were fabricated via the facile chemical
oxidative polymerization of pyrrole with high feeding ratio of sodiumalkane sulfonate (SAS). SAS was used as
the surfactant (template) and dopant for the nanostructured conductive polyme...

Water-dispersed polypyrrole nanospheres via chemical oxidative polymerization in the presence of castor oil sulfate
The castor oil sulfate (COS), produced by the sulfonation of the castor oil (one of the most promising
renewable sources), was used as both the surfactant and the dopant in the chemical oxidative poly-
merization of pyrrole. The resulting castor oil sulfate doped polypyrrole nanospheres (PPy/COS) were
characterized with FTIR, UV–vis, TGA, zeta potentials and TEM techniques. It was found t...

Water-dispersed polypyrrole nanoparticles via chemical oxidative polymerization in the presence of a functional polyanion
Poly(2-hydroxy-3-(methacryloyloxy) propane-1-sulfonate) (PHMPS), a polyhydroxyl sulfonate, was used
as both the template and the dopant in the in situ doping chemical oxidative polymerization of pyrrole.
The resultant PHMPS doped polypyrrole (PPy/PHMPS) nanoparticles were characterized with FTIR, UV–
vis, TGA, zeta potentials and TEM techniques. It was found that their size decreased and ...

Sensors and Actuators B: Chemical, 2011, 155, 584-591: Fabrication, structural characterization and sensing properties of polydiacetylene nanofibers templated from anodized aluminum oxide
Polydiacetylene (PDA), as a unique conjugated polymer, has shown its potential in the application of chem/bio-sensors and optoelectronics. In this work, we first infiltrated PDA monomer (10, 12-pentacosadiynoic acid, PCDA) melt into anodized aluminum oxide template, and then illuminated the infiltrated template with UV light to initiate the polymerization of PCDA. After etching away the aluminum o...

Influence of Nanotube Chirality, Temperature, and Chemical Modification on the Interfacial Bonding between Carbon Nanotubes and Polyphenylacetylene
Molecular dynamics (MD) simulations were used to study the interaction energy between single-walled carbon nanotubes (SWNTs) and polyphenylacetylene (PPA). The “wrapping” of nanotubes by PPA chains was
computed. The influence of nanotube chirality, temperature, and chemical modification on the interfacial adhesion of nanotube-PPA was investigated. The results showed that the interacti...

Chemical Modification: an Effective Way of Avoiding the Collapse of SWNTs on Al Surface Revealed by Molecular Dynamics Simulations
The rapid collapse of intrinsic single-walled carbon nanotube (SWNT) on the aluminum surface is observed using molecular dynamics simulation. The collapsing threshold is ∼10 Å, and the length has no influence on its collapse. Furthermore, we report that the structural stability of cylindrical SWNTs on the aluminum surface can be improved through the surface modification method. The stabi...
