About me

The aim of my Ph.D project was to improve electrical insulation materials and develop field-tuning materials of high-voltage cables and accessories by the self-assembly of surface-modified nanoparticles in polymer matrices forming superstructures or well-dispersed nanoparticles.

I have particularly been synthesising surface modifications of alumina, zinc oxide and graphene oxide nanoparticles using controlled radical polymerization. The surface-modified nanoparticles could be designed for various matrices and the inter-particle distance controlled.

Nanocomposite materials with thermo-responsive and field-grading functional properties were successfully developed and tested. Such materials are promising candidates as functional isolation materials in Smart Electric Grids, wearbles and energy-efficient applications.
