High voltage epoxy mica capacitor research and development

Is mica a good insulation material for high voltage rotating machines?

The investigation of mica and mica/epoxy-composites has always been of high importance and has gained increased attention in recent years due to their significant role as insulation material in the electrical industry. Electrical insulation represents a key factor regarding the reliability and lifespan of high voltage rotating machines.

Can pmma/2d nanocomposite be used for high-density energy storage capacitors?

This excellent capacitive and energy storage performance of the PMMA/2D Mica heterostructure nanocomposite may inform the fabrication of thin-film, high-density energy storage capacitor devices for potential applications in various platforms.

Why is thin-layer mica a good material for nanocomposites?

Thin-layer Mica has a high band gap [3–4 eV] and, along with its two-dimensional structure, offers a significant surface area for interaction with the polymer matrix, resulting in improved mechanical strength, thermal stability, and electrical insulation properties in nanocomposites .

Does a 2D mica nanofiller increase dielectric constant?

The incorporation of a 2D Mica nanofiller in the low-dielectric-constant PMMA leads to an enhancement in the dielectric constant, with ∆ε ~ 15% and 53% for PMP and PMPMP heterostructures at room temperature.

Is PMMA a good capacitor?

The PMMA exhibits a low value for both D r and D max, and high electric field sustainability varies between 400 and 750 MV/m. The capacitors also show minimum hysteresis loss. These combinations result in a moderate U d of 8 to 15 J/cm 3, while efficiency remains relatively high up to 80% [33, 37, 38, 39, 40].
