Reports from University of Naples Federico II Highlight Recent Findings in Polymer Science

May 23, 2014

By a News Reporter-Staff News Editor at Science Letter -- Current study results on Science have been published. According to news reporting from Naples, Italy, by NewsRx journalists, research stated, "Poly(butylene terephthalate) (PBT) is one of the most widely used semicrystalline thermoplastics polyester because of its superior thermal and mechanical properties, high dimensional stability and excellent processability."

The news correspondents obtained a quote from the research from the University of Naples Federico II, "In this research PBT-based nanocomposites, including various amounts (up to 10 wt%) of commercial alumina whiskers, have been prepared by using a Brabender internal chamber mixer and analysed in terms of morphological features and dielectric properties. Specific attention has been focused on the effect of the filler functionalization considering 3-glycidoxy propylmethoxysilane (GPS) or 3-methacryloxypropyltrimethoxysilane (MPS) as coupling agents."

According to the news reporters, the research concluded: "Tests, performed on compounds filled with neat and functionalized alumina whiskers, show a clear dependence of relative dielectric permittivity (epsilon(r).), invariance of dissipation factor (tg delta.), and a sensible increase of volume electrical resistivity (rho(v)) with the filler's content and are encouraging for a future introduction of such composites in many electrical applications."
