Graphene – Epoxy Composites for Anti-Corrosion Coatings

Bosnick K., Benhalima A., Chapleau N., Tefashe U.M., Bergren A.J., Yang Q., Champagne M.F., National Research Council Canada, CA

It is important to protect steel infrastructure, such as pipelines, from environmental corrosion. The primary method for this protection is by utilizing coatings, especially epoxy (EP) coatings. In recent years graphene has shown a great [...]

Polymer Matrix Nanocomposites via Forest Derived Nanomaterials

Schueneman G.T., Mintz E.A., Cross L., USDA Forest Service Forest Products Laboratory, US

Trees are a likely source of bioderived nanomaterials for polymer matrix composites (PMCs). All trees and plants utilize a nanoscale fiber as a building block in their reinforcing phase. The presence of nanofiber in cell [...]

Effect of Cutting Parameters on The Surface Roughness of MWCNT Reinforced Epoxy Composite Using End-Milling Process

Harii Krishna Rao G., Ansari M.N.M., Universiti Tenaga Nasional, MY

In this paper, the preparation and casting of sample composite, machining parameters and Scanning electron microscopy (SEM) studies on multi-walled carbon nanotubes (MWCNT) reinforced epoxy composites were discussed. Structurally, MWCNTs consist of multiple layers of [...]

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 [...]

Trifunctional Epoxy – SWNTs Composites. a New Non – Covalent SWNTs Integration Approach

González-Domínguez J.M., Ansón-Casaos A., Díez-Pascual A.M., Ashrafi B., Naffakh M., Johnston A., Gómez M.A., Martínez M.T., Instituto de Carboquimica (CSIC), ES

Properly dispersing CNTs within polymers, specifically egarding epoxy matrices, is extremely difficult. A novel non-covalent functionalization technique, in which a block copolymer (Pluronic F68) is used to wrap SWNTs, has been developed combining both concepts: [...]

Toughening mechanisms of nanoparticle-modified epoxy polymers

Mohammed R.D., Johnsen B.B., Kinloch A.J., Taylor A.C., Sprenger S., The University of Trinidad and Tobago, TT

An epoxy resin, cured with an anhydride, has been modified by the addition of silica nanoparticles. The particles were introduced via a sol-gel technique which gave a very well-dispersed phase of nanosilica particles which were [...]
