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...

Doping and De-doping of Carbon Nanotube Transparent Conducting Film by Dispersant and Chemical Treatment
Single-walled carbon nanotubes (SWCNTs) dispersed with Nafion in a solvent mixture containing deionized water and 1-propanol (bisolvent) were sprayed on a poly(ethylene terephthalate) substrate to fabricate flexible transparent conducting films (TCFs). Different SWCNT to Nafion ratios were used to optimize the film performance of transparence and sheet resistance. The TCFs were then immersed in ni...

Fabrication of a molecular-level multilayer film on organic polymer surfaces via chemical bonding assembly
A fresh multilayer film was fabricated on a molecular level and successfully tethered to the surface of a hydroxylated organic substrate via chemical bonding assembly (CBA). Sulfate anion groups (SO4-) were preintroduced onto the surface of biaxially oriented polypropylene (BOPP) films via a reference method. Upon hydrolysis of the SO4- groups, hydroxyl groups (--OH) were formed that subseque...
