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...

A Biomimetic Chemical Approach to Facile Preparation of Large-Area, Patterned, ZnO Quantum Dot/Polymer Nanocomposites on Flexible Plastics
This study reports a new biomimetic approach to fabricate ZnO quantum dots (QDs) directed by surface-immobilized acidic-polymer brushes. Through multiple characterization methods including XPS, high-resolution TEM, SEM, AFM, XRD, UV-vis absorption and fluorescence spectroscopy, we found that surface-photografted poly(acrylic acid) chains could mediate the heterogeneous nucleation and growth proces...

Study on the chemical modification of epoxy/anhydride thermosets using a hydroxyl terminated hyperbranched polymer.
Mixtures of diglycidylether of bisphenol A (DGEBA) resin and commercially available hyperbranched polyester (HBP) Boltorn H30 were cured by anhydride to covalently bond the hydroxyl end groups in HBP with the epoxy resin. The curing mixtures were investigated by Differential Scanning Calorimetr), (DSC) to study the curing evolution and to evaluate the kinetic parameters. DSC studies suggested that...
