By adding semiconducting nanoparticles to polymers, the
Materials + Technologies Research Group (GMT) of the Polytechnical College of
San Sebastian of the UPV/EHU-University of the Basque Country has created
nanostructured composite materials with specific optical and electrical
properties that vary according to size. These properties allow researchers to
synthesise particles of the size corresponding to the desired properties, and
by adding these particles to polymers, to give the final product one specific
property or another.
