Space Charge Behavior in Low-Density Polyethylene
The space charge distribution in low-density polyethylene (LDPE) was measured with the pulsed electroacoustic (PEA) method. We used three types of LDPE: LDPE-L and LDPE-H were prepared by the high pressure process, and m-LDPE was polymerized with a metallocene catalyst. Space charge in LDPE strongly depended upon the electrode material. Semiconductive electrodes enhanced carrier injection into ...
متن کاملSpace-charge dynamic in polyethylene: from dc to ac stress
Time-resolved space charge profiles obtained in low density polyethylene under sinusoidal or square AC stress for frequencies going from DC to 10 Hz, temperature from 25 to 50°C and fields of 30 or 40 kV/mm are presented. It is shown that most of the features observed under DC stress (generation of carriers of the two polarities with non-symmetrical amount and velocity) are still active under A...
متن کاملStretch-induced wrinkling of polyethylene thin sheets: Experiments and modeling
This paper presents a study on stretch-induced wrinkling of thin polyethylene sheets when subjected to uniaxial stretch with two clamped ends. Three-dimensional digital image correlation was used to measure the wrinkling deformation. It was observed that the wrinkle amplitude increased as the nominal strain increased up to around 10%, but then decreased at larger strain levels. This behavior is...
متن کاملThe influence of oxidation on space charge formation in gamma-irradiated low-density polyethylene
The research presented in this paper investigates the role of oxidation in the formation of space charge in gammairradiated low-density polyethylene after being electrically stressed under dc voltage. Polyethylene plaques both with and without antioxidant were irradiated up to 500 kGy using a Co gamma source and space charge distributions were measured using the piezoelectric induced pressure w...
