Article Synopsis
- Five types of nanofillers (silica, surface-silylated silica, alumina, surface-silylated alumina, and boron nitride) were tested in epoxy/amine resin nanocomposites to assess their dielectric properties, focusing on the effects of nanoparticle surface functionalization and water absorption.
- The research found that water absorption significantly impacted the insulating properties of the materials, with interfacial polarization increasing while the dielectric strength decreased, particularly in composites with silica.
- Among the tested composites, those with silylated alumina and boron nitride demonstrated the best dielectric performance, highlighting the importance of surface interactions with water.
The thermal, rheological, and mechanical behavior of copolymers of lactide, isosorbide, and three different phthalic acids are studied in a wide range of compositions. A linear behavior in glass transition temperature (Tg) with respect to the mole fraction of isosorbide and phthalate content in the copolymers is observed. This behavior is in quantitative agreement with the well-known Di Marzio-Gibbs equation, which correlates the Tg with the mole fraction of flexible bonds in the monomers.
