Polymer nanocomposites: an advanced material for functional fibers

Joshi M., Indian Institute of Technology, IN

The paper illustrates our development in the area of producing fibers from polymer nanocomposites both through melt and solution intercalation route. The polymers studied are Polypropylene, Polyethylene Polyurethane and Nylon. The naofillers used range from [...]

Structural Control of Porous Polymeric Materials through Magnetic Gelation

Furlan M., Lattuada M., Morbidelli M., ETH Zürich, CH

A novel procedure, called magnetic gelatio, is introduced to prepare porous polymeric materials with controlled anisotropic structure. The materials are obtained by destabilizing aqueous dipsersions of magnetic polymer nanoparticles in the presence of magnetic fields, [...]

Soft plasma polymer coatings based on atomic polymerization

Cech V., Trivedi R., Lichovnikova S., Hoferek L., Brno University of Technology, CZ

Plasma polymerization is a thin film-forming process based on atomic polymerization. Plasma polymer films deposited from organosilicon monomers constitute a special class of dielectric coatings with controllable organic/inorganic character and cross-linking that enable optimization of [...]

Directed assembly of magnetic nanoparticles in polymers: the formation of anisotropic plastic films containing aligned nanowires

Fragouli D., Buonsanti R., Villafiorita Monteleone F., Bertoni G., Sangregorio C., Torre B., Cingolani R., Athanassiou A., Italian Institute of Technology, IT

We present a study of the dynamical formation of spatially localized arrays of 1-D aligned magnetic nanowires in plastic films. We demonstrate a straightforward technique, easily reproducible, where by specifically varying experimental conditions we can [...]

ZnO:Polydiacetylene Films as Chromatic Sensors

Patlolla A., Zunino III J.L., Schmidt D.P., Iqbal Z., Skelton D.R., U.S. Army, US

Films of the conjugated polydiacetylenes (PDAs) can function as chromatic temperature, chemical and stress sensors, and can be prepared by spin-coating from monomer solutions followed by polymerization. The polymer backbone of PDAs is comprised of [...]

Synthesis and Application of nano-size polymer colloids at The Dow Chemical Company

Tucker C.J., The Dow Chemical Company, US

Over the last 50+ years The Dow Chemical Company has sponsored numerous research programs involving the preparation and use of nano-size colloidal systems. The nano-colloids used range from soft (liquid microemulsions) to solid (polymeric) materials [...]

Novel Composites of Carbon Nanotubes with a Poly(Phenylene Ethynylene) by Non-Covalent Wrapping for Photovoltaic Devices

Ramos J.C., Cortes P., Moggio I., Arias E., Martínez C., Moreno K.J., Universidad Autonoma de Ciudad Juarez, MX

Conjugated polymers exhibit optoelectronic properties comparable with those of inorganic semiconductors and with some advantage over them. By their side, carbon nanotubes (CNTs) offer a great opportunity for exciton dissociation. For this reason, the combination [...]

Electric Field Effect on the Rheology of MWCNT Dispersions in Liquid Crystalline Polymers

Cameron-Soto A.R., Acevedo-Rullán A., University of Puerto Rico-Mayagüez, PR

Carbon nanotubes (CNT) are ideal candidates for the development of nanocomposites. Nevertheless, to achieve their potential they should be dispersed and aligned with a specific orientation. Many techniques have been proposed to achieve these requirements [...]

Rigid Poly(vinyl chloride) / Halloysite Nanocomposites

Mondragón M., Roblero Y.S., Sánchez M.E., Zendejas B.E., ESIME-IPN Unidad Azcapotzalco, MX

Polyvinyl chloride (PVC)/ halloysite nanotubes (HNT) nanocomposites were prepared by melt blending of PVC with HNT. PVC masterbatch powders were first hand blended with 1, 3, 5 and 8% w/w of HNT and then melt-mixed [...]
