Silica Functionalization: How Does It Affect Space Charge Accumulation In Nanodielectrics Under DC?
Functionalization of silica nanoparticles with polar aminosilane and its effect on space charge accumulation under high voltage direct current (DC) was studied in polypropylene (PP)/ Ethylene-Octene Copolymer (EOC) /silica ...
Influence of polar and unpolar silica functionalization on the dielectric properties of PP/POE nanocomposites
This study focuses on the influence of polar and unpolar surface functionalization of silica on the dielectric performance of PP/POE (polypropylene/poly(ethylene-co-octene)) nanocomposites. The silica fillers were ...
Silica surface modification with liquid rubbers & functional groups for new polyolefin-based dielectric nano-composites
A novel hybrid approach for surface modification of nano-silica for polyolefin-based dielectric composites is presented. A fumed nano-silica was modified with long oligomeric chains of a liquid rubber, connected via urethane ...
Surface Modification of Fumed Silica by Dry Silanization for PP-based Dielectric Nanocomposites
Novel nanocomposites for dielectric applications based on a polypropylene (PP) blend filled with nanosilica are developed in the frame of the European `GRIDABLE' project. A systematic study of the influence of surface ...
Practical Notes on the Measurement and Interpretation of Thermally Stimulated Discharge Currents in Biaxially Oriented Polypropylene
(Nordic Insulation Symposium, 2019-08-08)
The measurement and interpretation of high-field thermally stimulated depolarization current (TSDC) of capacitor-grade biaxially oriented polypropylene (BOPP) films are investigated in order to facilitate the derivation ...
Cyclic Bending Reliability and Failure Mechanism of Printed Biodegradable Flexible Supercapacitor on Polymer Substrate
A flexible supercapacitor (SC) is an attractive energy storage device for powering low-power sensors, since it can be built using only nontoxic and sustainable materials. In this study, the advantages of using biodegradable ...
Pigment-Cellulose Nanofibril Composite and Its Application as a Separator-Substrate in Printed Supercapacitors
Pigment-cellulose nanofibril (PCN) composites were manufactured in a pilot line and used as a separator-substrate in printed graphene and carbon nanotube supercapacitors. The composites consisted typically of 80% pigment ...
