Synthesis of Nanoparticles by Crosslinking Copolymerization

Uveges A., Hartmann J.F., Borbely J., University of Debrecen, HU

Cross-linked polymers formed by free radical polymerization in homogeneous solution or in emulsion are used in many current and emerging applications, including dental materials, protective and decorative coatings, contact lenses, super absorbent materials and hydrogels [...]

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 [...]

Strain-induced Crystallization and Mechanical Properties of Carbon Nanotubes Reinforced Natural Rubber

Jeon H.-J., Kang M.K., Song H.H., Kwag G., Choi H., Hannam University, South Korea, KR

Natural rubber is an elastomeric material and its ability to crystallize at large deformations results in an extraordinary toughness. However, natural rubber needs the reinforcing materials to improve the mechanical strength, thermal stability and abrasion [...]

Nanostructured Polymeric Composites for High Performance Applications

Calhoun M., Allie A., Allie L., Allie A., Allie L., Aglan H., Dennig P., Tuskegee University, US

Nanostructured polymeric systems can mitigate some of the severe limitations of conventional polymeric composites. In the present research, nanocomposites of epoxy resins have been synthesized and evaluated. Organically modified layered silicate (OLS) particles and multiwalled [...]

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) [...]

Ferritin-based Hybrid Nanofibers with Magnetic Properties

Shin M.K., Cho Y., Kim S.J., Hanyang University, KR

There has been intense interest in polymeric nanocomposites using nanoparticles, nanowires, and nanotubes, because nanocomposites possess improved physical properties versus the unmodified polymer. In particular, a mixture of polymers and nanoparticles can form flexible nanocomposites [...]

Synthesis and Characterization of Novel Polyimide/TiO2 Nanocomposite System for the Application of Organic Electronics

Ahn T., Yu Y.I., Hong S.K., Yi M-Y, Korea Research Institute of Chemical Technology, KR

Organic/inorganic nanocomposites have become an effective source of advanced materials as they usually exhibit unique properties that traditional composites and conventional materials do not have. They combine the advantages of the inorganic material (rigidity, high [...]

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 [...]

Nanoparticles Prepared by Self-assembly of Chitosan and Poly-gamma-glutamic Acid

Bodnar M., Hajdu I., Filipcsei G., Hartmann J.F., Borbely J., University of Debrecen, HU

The technique of self-assembly of polyelectrolytes opens many new opportunities to achieve idea models as delivery system. The oppositely charged biopolymers can self-assemble by the attractive interaction between the functional groups. The electrostatic interactions between [...]
