Polymeric Coatings for Skutterudite-Based Thermoelectric Materials

Article is a study with the main objective of mitigation of thermal degradation of skutterudite-based thermoelectric materials—so as to extend the service life of those materials and make them more attractive for industry from the economical perspective. Significant mitigation of oxidation and sublimation of thermoelectric (TE) materials was achieved.

Effects of UV Stabilizers on Polypropylene Outdoors (open access)

Effects of UV Stabilizers on Polypropylene Outdoors

This article looks at hindered amine light stabilizers (HALSs) and nano ZnO were used to stabilize polypropylene (PP) film-based formulations that were exposed to ultraviolet (UV) light for different lengths of time, simulating the harsh outdoor weather of Dallas, Texas, USA. UV doses applied in our laboratory are 121 times larger than the UV dose provided by the sunlight in Texas. 15 different compositions were studied. The combination of HALSs and nano-ZnO stabilizers makes the PP films harder—which is important for some PP applications, such as toy manufacturing.
