Atomistic-Based Continuum Modeling of the Interfacial Properties of Structural Adhesive Bonds

Wernik J.M., Meguid S.A., Ruda H., University of Toronto, CA

This work is concerned with the multiscale modeling of nano-reinforced structural adhesive bonds (SABs) that are typically used in the transport industry, with the aerospace sector being the prime target. Specifically, it is our objective [...]

Functionalization of Carbon Nanotubes for Advanced CNT/LCP Nanocomposites

Sahoo N.G., Cheng H.K.F., Li L., Chan S.H., Zhao J., Nanyang Technological University, SG

A novel approach has been made to the chemical functionalization of multi-walled carbon nanotubes (MWCNTs) for developing advanced polymeric nanocomposites with liquid crystalline polymer (LCP). In the approach, we have selectively introduced two types of [...]

Poly(vinyl chloride)/TiO2 nanocomposite resin via the synthesis of TiO2 nanoparticles in vinyl chloride followed by in situ suspension polymerization

Yoo H., Kwak S-Y, Seoul National University, KR

Various methods are established and implemented to prepare polymer/TiO2 nanocomposites, but the choice of preparation method is limited in the case of most frequently used commodity polymers such as PVC, because of their enormous production [...]

Nanoparticle release from nano-containing product, introduction to an energetic approach

Gheerardyn L., Le Bihan O., Dore E., Morgeneyer M., INERIS, FR

The use of nanoparticles in manufactured products becomes more and more frequent and could lead to new potential risks for the workers, the consumers and the environment. This study focused on the R&D process of [...]

Developing a Strategy for the Spatial Localisation and Autonomous Release of Silver Nanoparticles within Smart Implants

Newton L.A.A., Sharp D.G., Leslie R., Davis J., Nottingham Trent University, UK

A novel approach to the controlled release of silver nanoparticles from a solid state repository within microdevice/micro fluidic architectures is presented. The dynamics of their formation, mechanism and influence on particle formation and release characteristics [...]

An analytical method to quantify the release of silica nanoparticles from polymer nanocomposites exposed to UV radiation

Rabb S.A., Yu L.L., Nguyen T., National Institute of Standards and Technology, US

Silica nanoparticles are being utilized to enhance the mechanical performance of polymeric coatings used in automotive and construction industries. However, cumulative effects of UV radiation will degrade the polymeric molecules, resulting in a potential for [...]

Direct Evidence of Nanoparticle Release from Epoxy Nanocomposites Exposed to 295 nm-400 nm UV Radiation

Nguyen T., Pellegrin B., Stutzman P., Shapiro A., Byrd E., Gu X., Chin J., NIST, US

Nanoparticles are increasingly used for enhancing multiple properties of polymers in many industries including construction, automobile, and aerospace. However, recent research suggests that nanoparticles might have negative effects on the environments and health safety. Since [...]

New method for the caracterization of abrasion-induced nanoparticle release into air from nanomaterials

Golanski L., Guiot A., Tardif F., CEA, FR

Nanotechnologies are emerging around the world. Nanoparticles are finding new industrial applications every day. Due to the variety of nanoparticles, toxicology studies will take time to establish the dangerousness of every kind of nanoparticle. Today [...]

Characterizing Nanoparticle Emissions from Burning Polymer Nanocomposites

Nyden M.R., Harris R.H., Kim Y-S, Davis R.D., Marsh N.D., Zammarano M., National Institute of Standards and Technology, US

At Nanotech 2009, we presented evidence that CNFs used as fire retardants in polyurethane foam (PUF), were destroyed in the flames and, therefore, were not released when CNF containing foams are burned under well-ventilated conditions. [...]

Surface tailoring of carbon fabric reinforced PES composites with micro and nano PTFE fillers

Sharma M., Bijwe J., Indian Institute of Technology Delhi, IN

Carbon fabric reinforced polymers (CFRPs) are being increasingly used as advanced composites for structural materials applications, especially in aircraft industry because of very high specific strength and modulus apart from their higher thermal conductivity, corrosion [...]
