Synthesis of a CNT Nano-Coating on Carbon Fibers: its Role on Strength, Toughness & Damage Tolerance of Polymer Matrix Composites

Prabhu-Gaunkar G., Indian Institute of Technology - Bombay, IN

Carbon in its form as nanotubes is an excellent candidate material for applications as reinforcement in advanced composites. The outstanding mechanical, electrical and thermal properties properties of these nano constituents can be transferred to macro-level [...]

Rapid one-step chemical synthesis of polyaniline-manganese ferrite nanocomposites without external initiator and mechanical agitation

Chimamkpam E.F.C., Schweizer T., Schilling A., Ferreira J.M.F., Centre for Research in Ceramics and Composite Materials, PT

We describe a rapid one-step, room temperature method to chemically synthesize bulk quantities of nanocomposites comprising specifically of manganese ferrite (MnFe2O4) and polyaniline (conductive form). Typically a chemical agent, for example ammonium peroxydisulfate, is used [...]

Characterization of Nanoparticle Release from Polymer Nanocomposites Due to Fire

Uddin N.M., Nyden M.R., National Institute of Standards and Technology, US

Studies are being conducted to understand the potential hazards associated with burning materials containing carbon nanotubes (CNTs) and nanofibers (CNFs) either in the process of incineration or in accidental fires. Some of the important questions [...]

Magnetic assisted self-assembly

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

In this work, we introduce a new technique to produce anisotropic porous materials called magnetic assisted self-assembly. This method takes advantage of the alignment in the presence of a magnetic field of non-magnetic colloidal nanoparticles, [...]

Fabrication and Testing of Three-Dimensionally Reinforced Carbon Nanotube Based Laminated Nanocomposites

Askari D., Ghasemi-Nejhad M.N., The University of Texas at Brownsville, US

Carbon nanotubes (CNTs) can be used for the reinforcement of polymers to create novel nanotube based nanocomposites with tunable properties and multifunctional behaviors. Chemical vapor deposition technique is employed to grow vertically aligned high density [...]

Characterization of palladium nanoparticles embedded in a wool substrate

Fonseca-Paris C., Johnston J.H., Victoria University of Wellington, NZ

In the present paper we report the characterization of nanopalladium-wool fibre composites. Professor James Johnston and his research group at Victoria University of Wellington have developed a new methodology to reduce metal salts of palladium [...]

Enhancing mechanical properties of epoxy resin while reducing viscosity using “liquid nano-reinforcement”

Zhong K., Washington State University, US

Graphitic carbon nanofibers (GNFs) were first made into a “liquid nano-reinforcement” (LNR) that is composed of reactive nanofibers (r-GNFs) and an epoxy diluent through chemically reacting the functionalized GNFs with the diluents. Due to the [...]

Polymer Nanocomposites from Functionalized Polyolefins

Paul D.R., University of Texas at Austin, US

Polymer-layered silicate nanocomposites formed from the organically modified clay mineral montmorillonite and related materials have attracted a great deal of technological and scientific interest in the past decade. These composites offer the promise of greatly [...]

Mechanical Reinforcement of Epoxy Resins using Magnetic Aligned Halloysite

Mendoza-Bello S., Barrientos-Ramirez S., Montes de Oca G., Flores-Santos L., Macro-M, S.A. de C.V., MX

In this work we report the synthesis of magnetite nanoparticles using halloysite as template. Halloysite is treated using a two steps activation method (Sn/Pd) and in a third step ferrite is formed using a coprecipitation [...]

Release-ability of nano fillers from different nanomaterials

Tardif F., Golanski L., Guiot A., Pras M., CEA-Grenoble, FR

The nanoparticles are finding new industrial applications every day in fields as diverse as electronics, biomedicine, pharmaceutics, cosmetology, chemical catalysis, new materials, and others. We are about to witness the advent of a new era [...]
