Polymer nanoparticles. Physical properties and possible applications

Abstract:
Polymer nanoparticles and their dispersions in water have applications in many scientific fields including photonics, adhesives or biomedicine. In addition to the advantage of using water as the primary continuous phase, functional inks composed of polymer nanoparticles offer a highly effective area and size and structural tunability by playing with preparation conditions. In this talk we will describe methodologies for the formation of nanoparticles using “preformed” polymers, i.e., commercially available systems with low polydispersity index, high purity, and traceability. Using these sorts of polymers as precursors allows to compare physical properties of the polymer in the confined state as compared to its bulk properties. Besides, polymer nanoparticles prepared from functional polymers open new possibilities for applications due to the possibility of tuning functionality in the nanoparticles. The case of ferroelectric polymer nanoparticles and semiconducting polymer nanoparticles will be presented.

Aurora Nogales is Doctor in Physics and works as a senior scientist at Instituto de Estructura de la Materia, IEM-CSIC. She was vicedirector of this center in 2009 and 2010. Previously she worked at StonyBrook State University of New York, and at the Physics Department of Reading University, UK. She has been also visiting scientist at the Center for Functional Nanomaterials in Brookhaven National Lab. Her expertise is centered around the interplay between dynamics and structure in polymer science by using different experimental techniques like dielectric spectroscopy, synchrotron radiation techniques and neutron scattering. She was promoter of the proposal for the construction on NCD-sweet beamline at ALBA relationships between properties, structure and dynamics in polymers. She has recently focused this expertise on functional polymers with applications in energy. She is author of around 140 papers and editor of two books on topics related to dielectric spectroscopy and X ray scattering in polymers using synchrotron.
