The case involving Low-density Polyethylene (LDPE) containing nano-MgO is revisited here with the main aim of verifying the effect of the fabrication technique. LDPE powder and MgO unfunctionalized nanoparticles were used in conjunction with an impact ball-milling method. Samples consisting of neat LDPE and nanocomposites containing 1 and 5 wt% of MgO were prepared. Several material and dielectric...
This work deals with the study of epoxy composites containing Si/SiO2 core/shell nanoparticles for insulation applications. Neat epoxy and epoxy based samples filled with micro and/or nanometric Si/SiO2 core/shell particles were characterized by scanning electron microscopy (SEM), differential scanning calorimetry (DSC), dielectric spectroscopy, dynamic mechanical analysis (DMA) as well as erosion...
Whether the surface resistance to erosion of a polymer nanocomposite system containing a conductive phase could be affected is the topic of this contribution. In order to answer this question, two material systems were fabricated and studied. Low-density polyethylene (LDPE) was prepared using ball-milling with Graphene Oxide (GO) up to 0.3 wt%. Epoxy resin was mixed with Carbon Black (CB) up to a...
Low-density polyethylene (LDPE) nanocomposites containing oibPOSS were prepared using ball-milling as a fabrication technique. POSS is basically molecular SiO2. Here it was used up to 5 wt%. At low content, it was found to disperse well into the matrix yet, as the content increases, it was observed to form polycrystals. In general, neat LDPE properties benefit from the presence of the nanofiller....
