Polymer based Nanocomposites
Nanocomposites are novel materials with drastically improved properties due to the incorporation of small amounts (less than 10 wt%) of nano-sized fillers into a polymer matrix. These nanofillers can dramatically modify the mechanical, thermal and other properties (e.g. flame resistance, barrier properties, electric conductivity) of polymers.

Our present areas of interest in the field of nanocomposites are:
  • Magnetic shielding at high electromagnetic frequencies.

  • Plastics with magnetic properties

  • Plastic with electrical properties

  • Nanocomposites containing nanofibers as mechanical reinforcement.

  • Nanocomposites made up of biodegradable polymers.

  • Polymers with bactericidal properties

  • Nanocomposites with improved barrier properties (heat or mass diffusion)

Our work involves the synthesis of nanomaterials with tailored properties, or, alternatively, the modification of natural/commercial nanofillers in view of the desired end application. We study the polymer-nanoparticles interaction in order to improve the dispersion of nanomaterials (metal and ceramic nanoparticles, ceramic nanotubes) and ultimately have a better control on the properties of the nanocomposite. This generally involves optimization of materials preparation methods and/or functionalization of their surfaces. We are also investigating the use of nano- and microcapsules in polymers as chemical-eluting agents, and in this case a key aspect is controlling the porosity of the capsules, as this affects the loading capacity and release kinetics.
