“…The same tendency was reported in the literature for LDPE films [12]. Another tendency reported in the literature [13] is the time to breakdown decreasing linearly with increasing temperature under DC applied electric field. In this study it was found that the time to breakdown decreases with increasing temperature, see Table 1 for the data for the unfilled reference material.…”

<p>The current through the poly(ethylene-co-butyl acrylate) with 13 wt% of butyl acrylate (EBA) filled with 6 wt% of alumina nanoparticles with an approximate diameter of 45 nm was studied under constant stress application. The particles were either unmodified or surface-treated with aminopropyltriethoxy silane. The current was measured either until breakdown or for maximum stress duration of 10 minutes. Two voltage levels were chosen: 15 and 22.5 kV, which were low enough not to cause a breakdown during the ramping of the voltage at the rate of 490 V/s to the constant voltage level at room temperature. Several ramping rates {100, 260, 500, 1007} V/s were also tested for the reference unfilled material to evaluate its influence on the time to breakdown. Several temperature levels were tried: 20 (room temperature), 40 and 50 ºC.<br />As expected, higher applied voltage caused higher current through the materials, while higher temperature caused earlier breakdown as well as higher current. At the lower voltage level most of the materials survived the testing. At the higher voltage level most of the samples of the unfilled reference material failed at the temperatures above room temperature while most of the nanocomposite samples survived the testing even at higher temperatures.</p>

“…At first, a study on the effect of space charge formation under polarization by PEA on Kapton®-H using high electric field (from 110 up to 150 kV/mm) shows that heterocharge accumulates slowly until the breakdown occurs. This effect seems to be accelerated by the temperature when it is increased from 30 to 80°C [53]. Even long short-circuit period could not help to recover initial condition.…”

Polyimide (PI) is an interesting material for space applications as it offers excellent thermal properties. However, due to its dielectric properties, charge storage and release can be at the origin of electrostatic discharges that are hazardous for the surrounding electrical equipment. Depending on the spacecraft orbit, it is necessary to study the impact of specific surrounding environment. In any cases, the effect of vacuum and temperature variations can be combined with electrons and protons' irradiation, atomic oxygen erosion, and photons impact from UV exposure. On the market, there exist many types of PI, and since several years, composite are also developed. The main properties that are usually observed are the conductivity that is analyzed from surface potential decay, the photoemission and the ability to initiate and propagate surface flashover. Since several years, the space charge storage analysis by the pulse electro-acoustic method has been developed as an interesting complementary tool. It is important to remember that experimental characterization needs to be representative to the space environment especially because it has been observed that PI can recover its original properties in air in a couple of hours depending on the ageing degree.

“…Some studies have been carried out on insulating property of polyimide films [3][4][5][6][7][8][9]. It has been found that space charge can have a major effect on dielectric properties and is the main reason leading to dielectric breakdown [10,11]. Bellomo et al have found that the lifetime of insulating materials used in variable-frequency motors was mainly affected by the partial discharge.…”

In recent years, the multilayered polyimide films have been widely used in flexible PrintCircuit Board in order to reduce the thickness of the combination of the flexible PrintCircuit Board. The existence of space charge as a main reason for dielectric breakdown, has a great effect on breakdown characteristic. So it is important to study the space charge characteristics of the multilayered polyimide films. Fluorination can change the chemical component in surface layer of polymers and therefore can influence the charge injection from electrodes and affect the electrical properties of the surface layer. This paper presents a study aimed at clarifying the effect of fluorination on space charge behavior in multilayered polyimide films. Samples were fluorinated in a laboratory vessel at 328 K (55 ℃) using a F 2 /N 2 mixture with 20% F 2 by volume and 0.05 MPa (500 mbar) for respectively 15, 30, 45 and 60 minutes. The surface chemical compositions of the films were characterized by attenuated total reflection infrared analysis. The space charge distributions in multilayered polyimide films were measured by using the pulsed electroacoustic (PEA) method. Obtained results showed that the space charge distribution of multilayered film stacking with five fluorinated samples was quite different from that of multilayered film stacking with five untreated samples. It is also suggested that the fluorination can significantly suppress the injection of space charge.
