Title: Magnetic Nanofluid - Unsaturated Polyester Nanocomposites
Published In: Proceedings of the MATERIAIS 2007 Porto, 1 - 4 April 2007, Porto – Portugalia, POSTER
Description: Abstract: The attention given to research on nanocomposite systems is to a great extent a consequence of the potential to introduce significant changes in material properties with low contents of nanosized functional additives. In this work, nanocomposite systems based on an unsaturated polyester resin host and a nanosized phase consisting of a magnetic nanofluid (MNF), are manufactured and characterized. The use of two liquid phases - MNF’s and liquid prepolymers – provides a simple fabrication procedure of polymer based nanocomposites. Mixing of the MNF with the liquid resin while retaining the colloidal stability of the nanofluid, may lead to a good dispersion of the magnetic nanoparticles within the resin matrix. In view of the magnetic properties of nanoparticles, application of a magnetic field during the polymerization process enables the production of composites with an ordered nanostructure, as the result of chain-like ordering of nanoparticles, due to both magnetic field –magnetic dipole and dipole – dipole interactions. An objective of this work is to give insight into future research using MNF’s to aid in composites processing technologies such as resin transfer molding (RTM).
