Ordered Structure Pattern on Polymeric Surface

Liu T.H., Huang C-L, Lee S., National Tsing Hua University, TW

The wrinkle pattern on polymeric surface is explained by chemical stresses. We solved the anomalous transport equation to obtain the concentration of solvent in polymeric film. The anomalous transport consists of case I and case [...]

Computer modeling of complex block copolymer micelles with metal-ligand self-assembly

Wang Z., Dormidontova E.E., University of Connecticut, US

For many applications of nanostructured materials it is essential to understand the principles controlling self-assembly, which is often a challenging task due to the heterogeneity of building blocks, (different chemical nature, size, shape, deformability, etc.) [...]

A Novel Application Technique for Polymer Nanofibers in the Construction Industry

Araya A.L., Vargas R.F., Cuevas R., Chaves J.S., Instituto Tecnologico de Costa Rica, CR

During 2008 about 3 billion tons of concrete were produced all over the world, making it the most important industrial product produced in the history of mankind. Therefore, any technological improvement in this product will [...]

A Study of the Effect of Al2O3 Nanoparticles on the Cure behavior of Bisphenol A Epoxy Resin

Halim S.F., National Institute for standards, EG

Epoxy resins based composites are used as laminates for printed circuits boards, aerospace, ballistic and engineering hardware components, automotive parts, electrical components and rehabilitation products. However, some of its interior characteristics such as thermal stability, [...]

Toughening of epoxy matrix fiber reinforced composites with two different nanorubber systems for Advanced Industrial Applications

Ozdemir N.G., Zhang Tao, Kingston University London, UK

Toughening of commercial resin matrices with nano carboxylated acrylonitrile butadiene rubber (CNBR-NP) and acrylonitrile butadiene rubber (NBR-NP) was investigated. Different processing techniques have been used. The rheological, cure, mechanical and morphological characteristics of both systems [...]

Effect of Dispersion Conditions on the Thermo-Mechanical Properties of Functionalized Carbon Nanotube-Reinforced Vinyl Ester

Sabet S.M., Mahfuz H., Hashemi J., Florida Atlantic University, US

To date, controlling the microstructure of carbon nanotube (CNT)-polymer composites remains a challenge due to high tendency of CNTs to aggregate. Proper dispersion of CNTs in the matrix has to be guaranteed to employ CNTs [...]

Probing Critical Particle to Polymer Size Ratios for Non-Einstein Behavior in Polymer Nanocomposites

Schmidt R.G., Gordon G.V., Swier S., Cosgrove T., Dow Corning Corporation, US

Enhanced studies of polymer nanocomposites(PNCs)has led to multiple discoveries of PNC's that exhibit viscosity behavior counter to the classical behavior for filled systems originally defined by Einstein(1). Opposed to the viscosity increase typically observed for [...]

Quatsomes: highly stable nanovesicles formed by sterols and

Ventosa N., Ferrer-Tasies L., Moreno-Calvo E., Cano-Sarabia M., Aguilella-Arzo M., Angelova A., Lesieur S., Ricart S., Veciana J., Faraudo J., CSIC, ES

Thermodynamically stable nanovesicular structures are of high interest for academia and industry in a wide variety of application fields, ranging from nanomaterials preparation to nanomedicine. Here we show the ability of quaternary ammonium surfactants and [...]

Antioxidant and Antiradical SiO2 Nanoparticles Covalently Functionalized with Gallic Acid

Sotiriou G.A., Deligiannakis Y., Pratsinis S.E., ETH Zürich, CH

Gallic acid (GA) and its derivatives are natural polyphenolic substances widely used as antioxidants in nutrients, medicine and polymers. Here, nanoantioxidant materials are engineered by covalently grafting GA on SiO2 nanoparticles (NPs). A proof-of-concept is [...]
