Cobalt iron-oxide nanoparticle modified poly(methyl methacrylate) nanodielectrics

Epoxy nanodielectrics fabricated within situandex situtechniques

“…Since the employed nanoparticles are TiO 2 , with significantly higher dielectric permittivity than the base resin, local electric field distribution becomes smooth and each particle acts as a field diversion point assuming that the electric field landscape in the resin is not uniform [22]. Then these diversion points would screen the undesired effects of the defects or in other words smooth the electric field landscape -this would create a nanocomposite material that is defect tolerant.…”

“…Notice that there is a large drop in the breakdown scale parameter between ex situ and unfilled due to the surfactant material used in the in-house nanoparticle synthesis. The surfactant has ionic species that influences the high-field behaviour of the nanocomposites [22] because of the large changes in the local electric field distribution in the bulk of the sample. The fluctuations in the local electric field result in high stress Failure probability Failure probability E field (kV/mm) E field (kV/mm)…”

Polymer Based Nanodielectric Composites

“…The maximum energy density from the nanodielectric engineering so far is 15 J/cc. Recently, very fine TiO 2 nanoparticles were synthesized using self-assembling method (Tuncer et al 2009). The breakdown strength of the composites was increased by >20%.…”

Polymer-grafted magnetite nanoparticles via a facilein situsolution radical polymerisation

“…In the last decades, magnetic nanoparticles have been widely investigated because of their unique properties compared with bulk material and their potential applications [1,2], such as cancer therapy [3], biomedicines [4], drug delivery [5], biosensors [6], molecule detection [7], immobilisation of enzymes [8], catalysts [9], adsorbents [10], nanodielectrics [11] and so on. For many applications, the control of surface functionality is a key for controlling the nanoparticles' interaction with biological species, self-assembly dispersion and compatibility with polymeric materials [12].…”
