Frequency Dependence of Electroluminescence Measurement in LDPE [PDF]

International Journal of Electrical and Computer Engineering (IJECE), 2017
A good insulator for high voltage cable has low dielectric loss, reasonable flexibility and thermo-mechanically stable. However, prolonged application of electrical stresses on the cable will degraded the cable; physically and morphologically.

Crystallization morphology and space charge property of silica/low density polyethylene composites

AIP Advances, 2020
The accumulation of space charge in polymer insulation limits the development of high-voltage direct current transmission and reduces the service lifetime of power equipment. The electrical properties of polymers are affected greatly by their crystalline

Enhanced Formation of Dicarboxylic Acids in the Catalytic Oxidation of Polyethylene With O2 and NOx

Angewandte Chemie, EarlyView.
The oxidation of polyethylene in the presence of a mixture of O2 and NOx and with Cu2+/V5+ as catalyst yields ∼51 mol% diacids, while retaining ∼80 mol% of the carbon in the oil fraction. The developed method is robust and tolerates several polymer types as well as impurities.

On comparison of recycled LDPE and LDPE–bakelite composite based 3D printed patch antenna [PDF]

, 2021
In the past two decades number of studies have been reported on the use of thermoplastics as a substrate for 3D printed patch antennas. However, no work has been reported on the thermoplastic-thermosetting composite-based substrate for 3D printed patch ...

Charge Transport and Space Charge Formation in Low-Density Polyethylene [PDF]

, 2000
In the low-density polyethylene prepared by the high-pressure process (LDPE) and in that polymerized by using the metallocene catalyst (m-LDPE), homo space charges with same polarity as the semiconducting electrode were observed.

Effect of Zr-doped CaCu3Ti3.95Zr0.05O12 ceramic on the microstructure, dielectric properties, and electric field distribution of the LDPE composites

e-Polymers, 2023
Small-size CaCu3Ti3.95Zr0.05O12 enhanced dielectric constant of LDPE by 88.5% due to enhancing interfacial polarization included by ultrahigh interfacial area (∼3.0 × 105 m2) and played a prominent role in homogenize electric field distribution in LDPE ...
