Optical, Structural, and Dielectric Properties of Composites Based on Thermoplastic Polymers

As a result of the research activities being carried out within 4DPrinten project, new knowledge continues to be generated about optical, structural, and dielectric properties of composites based on thermoplastic polymers of the Polyolefin and Polyurethane type and BaTiO₃ nanoparticles.

In an article (that can be found here) recently published in Materials, researchers from INFM, All Green and Izertis explain how new films containing composite materials based on blends of thermoplastic polymers of the polyurethane (TPU) and polyolefin (TPO) type, in the absence and presence of BaTiO₃ nanoparticles (NPs) with the size smaller 100 nm, were prepared. Also, the vibrational properties of the free films depending on the weight ratio of the two thermoplastic polymers were studied. As a result, it was demonstrated that these films are optically active, with strong, broad, and adjustable photoluminescence by varying the amount of TPU.
