Assoc. Prof. Richard T. Olsson

Polymer Nanocomposite Materials in Emerging Applications

Dr. Olsson earned his PhD in 2007 at the Royal Institute of Technology (KTH) on the topic of microwave absorbing nanocomposites developed for the Swedish Research Defence Agency. Previous to the doctoral studies he had developed an interest in polymeric materials when working with optical fibre coatings at École Nationale Supérieure de Chimie de Montpellier in France (-2000) and at Bell Labs, USA (2000–2001). Olsson's doctoral studies on magnetic nanoparticles dispersions in thermoset polymers (2002-2007), were followed by works devising a system for fabrication of nanofibre reinforced silicone materials for Mölnlycke Health Care AB  (2007-2008). These nanocomposites were developed at the Stellenbosch University, South Africa. Postdoctoral studies were carried out 2008-2010 at Consejo Superior de Investigaciones Científicas (IATA), Spain, with focus on renewable nanomaterials within bioplastics for food packaging. In 2010 he returned to the KTH to pursue in depth development of nanocomposite polymer engineering processing at the Dept. of Fibre and Polymer Technology.

Dr. Olsson is currently co-supervising 5 PhD students under the division chief Prof. Ulf W. Gedde. The main research focus is directed towards novel nanocomposites materials and the interfaces between inorganic nanoparticles and polymers (inorganic and organic). A strong focus is directed towards the realization of nanocomposite materials into functional prototypes and Olsson has 5 worldwide patents in the above related field.

Projects and Interests

Main focus: Polymer nanocomposite fabrication (thermoplastics, thermoset and biobased) with rapid turnover polymer formulation investigations, surface adaption of nanoparticles to polymer interfaces, in-situ formation of nanoparticles, extrusion and electrospinning for anisotropic/isotropic composite fabrication. 

Additonal expertise: Inorganic metal oxide crystal synthesis, aqueous nanoparticles preparation, cellulose crystal extractions, (±) nanoparticle coating stabilization by covalent/adsorption assemblies, and miniature reaction technologies are topics of interest. 

Direction: Dielectrics, magnetics, ultrathin fiber systems (electrospinning), thincoatings and porositiy preparation strategies, for use in applied reseach materials investigations.
