Controlled Dispersion of Carbon Nanotubes by Amphiphilic Polyelectrolytes

Controlled Dispersion of Carbon Nanotubes Wrapped in Amphiphilic Block Copolymers: Elaboration of Polymer Nanocomposite

In this work, we aim to prepare polymer nanocomposites by the dispersion of multiwall carbon nanotube (MWCNT) in aqueous solution using amphiphilic block copolymers. First, we report our success in wrapping MWCNT with amphiphilic block copolymers in aqueous solution. We selected poly(ethylene oxide) (PEO) as the hydrophilic block because of its strong affinity for water and its easiness synthes...

Polyelectrolytes: Influence on Evaporative Self-Assembly of Particles and Assembly of Multilayers with Polymers, Nanoparticles and Carbon Nanotubes

Assembling polyelectrolyte multilayers in a bottom-up approach is reported for polymers, particles, nanoparticles, and carbon nanotubes. Effects of polyelectrolyte multilayers on evaporative self-assembly of particles, which are of interest to a number of applications including photonic crystals, films and substrates, are investigated. Polyelectrolyte multilayer coatings bring multifunctionalit...

Modeling the binding of peptides on carbon nanotubes and their use as protein and DNA carriers

An in deep study of the functionalization of carbon nanotubes for their application as peptides and DNA carriers is presented. Designed amphiphilic polypeptides are used to study the dispersion properties of single-walled carbon nanotubes (SWCNTs) and to measure the properties of the carbon nanotube-polypeptide complexes. These properties allow the design of methods for using carbon nanotubes a...

Increasing flexural strength and toughness of cement mortar using multi-walled Carbon nanotubes

In this study the effect of using multi-walled carbon nanotube (MWCNT) on flexural and compressive strengths, ultimate displacement and energy absorption capability of standard cement mortar considering different weight percentages of nanotubes as well as different dispersion methods has been investigated. Influential point in adding nanotubes to the composites is their proper dispersion, which...
