Manufacturing techniques can have a significant impact on the dielectric properties of nanostructured materials, sometimes even larger than the effect of the nanofiller itself. Indeed, the choice of the best nanofiller to improve the electric behavior of the final nanocomposite is often frustrated by residual contaminants of the matrix-nanofiller compatibilization process, moisture absorption, nanofiller...
Previously we have reported the existence of small-amplitude charge pulses in crosslinked Polyethylene (XLPE) and epoxy resin with a mobility several orders of magnitude higher than that found for the incoherent charge transport relevant to the steady state current. Here the relationship of this phenomenon to mechanical relaxation in the material is investigated by using a series of epoxy resin nanocomposites...
Electrospinning technology is attracting increasing interest for the fabrication of several polymeric and inorganic nanofibrous materials useful for a wide range of applications. Although the intensive research performed to understand the physics of the electrospinning process, control of polymeric jet path and of fibre deposition still remains a challenge. In this work, micropatterned electrospun...
