Is polypropylene a good material for film capacitor?

Polypropylene (PP) is the state-of-the-art dielectric material for film capacitor. However, the further progress of PP is impeded by its low permittivity and low energy storage density. Adding high-permittivity (high-k) nano-filler into PP matrix to prepare nanocomposites turns out to be a promising approach.

Does polypropylene improve dielectric and capacitive performance up to 120 °C?

Here we demonstrate a molecular semiconductor-grafted polypropylene (PP) composite that possesses substantially enhanced dielectric and capacitive performance up to 120 °C by virtue of the modulated carrier transport behavior.

Do dielectric constant and loss affect energy storage properties of capacitor films?

Dielectric constant and loss are extremely important dielectric properties, which have a significant effect on the energy storage properties of capacitor films. The dielectric constant and loss factor (tan δ) of samples were measured and the results are shown in Fig. 7.

Does metal deactivator affect dielectric properties of polypropylene composite films?

In this paper, polypropylene (PP) composite films modified with the metal deactivator (MD) are prepared in order to suppress the adverse effect of metal ashes on the dielectric properties.

What are dielectric film capacitors?

1. Introduction Dielectric film capacitors are fundamental components for electrical charge storage and control in electronic equipment and power systems by virtue of their superior reliability [, , , , ].

What is the dielectric constant of polypropylene grafted maleic anhydride (pp-G-Mah)?

The PP-g-0.5 (2.36) possesses a comparable dielectric constant with that of the PP+0.5, which is higher than the original PP (∼2.15), due to the partial polarity brought by the polypropylene grafted maleic anhydride (PP-g-MAH) and the effectively intensified polarization of the well-contacted filler/matrix interface region.
