Novel Manufacturing Technology of Polymeric Nanocomposites Using Supercritical Fluid Process

Jung H-T, Hong Y., Lee H., Lee S., Lee H., Lee S., Park M., Kim J., Lim S., Korea Institute of Science & Technology, KP

The increasing interest during the last few decades in decreasing the environmental effects of the release of organic compounds and aqueous waste has motivated the development of polymeric materials in supercritical fluids(SCF). However, the advantages [...]

Thermal and Electrical Characterization of Polypropylene/Carbon Nanotubes Nanocomposites

Pandis Ch., Logakis E., Chorianopoulos M., Spanoudaki A., Kyritsis A., Peoglos V., Pissis P., Micusík M., Krupa I., Omastová M., Pionteck J., Pötschke P., National Technical University of Athens (NTUA), GR

The influence of multi-walled carbon nanotube (MWCNT) content on electrical/dielectric and thermal properties of CNTs-reinforced polypropylene (PP) nanocomposites is studied. We focus on the investigation of electrical and dielectric properties in relation to percolation: ac [...]

Synthesis and Characterization of Recycled Polycarbonate/Organo-montmorillonite Nanocomposites

Basilia B.A., Casano A.I.Y., Gan J.W., Mapua Institute of Technology, PH

This study aims to synthesize and investigate the electrical, chemical and thermo-mechanical properties of recycled polycarbonate/organo-montmorillonite nanocomposites. Polycarbonate from post-consumer wastes was recovered by mechanical abrasion process and chemical stripping. Formulations of 1-10% organo-montmorillonite (o-mmt) [...]

Physical Properties of Ferrite Nanocomposites Based On Nylon-66

Kim B.C., Kim M.H., Kim B.C., Kim M.H., Hanyang University, KR

The ferrite nanoparticles acted as a nucleating agent, leading to a small degree of supercooling. However, above a critical loading level (1 wt %), the nanoparticles in the polymer matrix might restrict the chain mobility [...]

Thermal and Electrical Properties of Polyamide/Multi-Walled Carbon Nanotubes Nanocomposites

Logakis E., Pandis Ch., Kanapitsas A., Peoglos V., Pissis P., Pionteck J., Pötschke P., Micusík M., Omastová M., National Technical University of Athens (NTUA), GR

In the present work we investigate the influence of multi-walled carbon nanotubes (MWCNTs) on the thermal and electrical properties of a polyamide 6 (PA6) matrix by differential scanning calorimetry (DSC) and dielectric relaxation spectroscopy (DRS) [...]

Innovative PMMA/Silica nanocomposites for optical and biomedical applications

Avella M., De Petrocellis L., Di Pace E., Errico M.E., Gentile G., Orlando P., ICTP-CNR, IT

The main goal of this research is the preparation of new PMMA/Silica nanocomposites with improved mechanical properties and highly specific bio-activity. PMMA based nanocomposites reinforced with modified silica nanoparticles have been prepared and characterized. Transparency [...]

Huang C-C, Hosokawa Micron Powder Systems, US

The development of nanotechnology is closely related to the new economy full with high tech products towards 21st century. As a new material, the nanoparticle has certainly caught the imaginations of researchers around the world. [...]

Polypyrrole-Organoclay Nanocomposites for Gas Sensors

Magaraphan R., Thuimthad A., Chulalongkorn University, TH

Polypyrrole (PPy) was synthesized in the presence of octadecylammonium-montmorillonite (OC-MMT) 1-9 wt% using ferric chloride as an initiator to result the intercalated nanocomposites. The synthesized PPy and its nanocomposites were tested for volatile organic gases; [...]

The Center for Accelerated Applications at the Nanoscale

Decker S., Center for Accelerated Applications at the Nanoscale, US

The Center for Accelerated Applications at the Nanoscale (CAAN), established in 2004 by Governor Mike Round’s 2010 Initiative, is a group of distinguished South Dakota researchers who have joined together in focused efforts to conduct [...]

The Effect of Nanoparticle Distribution on The Structure and Properties of Palladium/Polycarbonate Nanocomposites

Atre S.V., Valmikanathan O.P., Pillai V.K., Mulla I.S., Ostroverkhova O., Oregon Nanoscience & Microtechnologies Institute, US

We report the synthesis of palladium (Pd)/polycarbonate (PC) nanocomposites as well as their morphological, thermal, optical and electrical properties. Pd nanoclusters were produced by the reduction of palladium chloride using a variation of the Brust’s [...]
