Abstract :
An electric strength (ES) test campaign in alternated current and space charge (SC) measurements via the pulsed electro-acoustic (PEA) method has been carried out on films of low-density polyethylene (LDPE) nanocomposites. The nanocomposite materials were obtained by the dispersion by melt mixing of organically modified layered silicates in an LDPE matrix. Before the electrical tests, the materials were characterized by means of X-ray diffraction (XRD) and thermogravimetric analysis (TGA). The LDPE-silicate nanocomposites evidenced some smart behaviour in AC.
