Enhanced Spin Transport of Conjugated Polymer in the Semiconductor/Insulating Polymer Blend

ACS Applied Materials & Interfaces, 2020
Conjugated polymers are of high potential in the development of spintronic devices. In this paper, we report systematic studies on spin transport properties of a semiconducting polymer PBDTTT-C-T in the permalloy/polymer/Pt trilayer using the spin pumping method.

Impacts of corona rings on the insulation performance of composite polymer insulator strings

IEEE Transactions on Dielectrics and Electrical Insulation, 2015
Corona rings can improve the insulation performance of insulator strings because of their electric field grading property or can decrease the insulation performance due to their arc clearance reduction property. The resulting insulation performance of the string which is under the influence of those two conflicting effects depends on the corona ring ...

Partial discharge degradation at insulating polymer-polymer interface

Proceedings of 1998 International Symposium on Electrical Insulating Materials. 1998 Asian International Conference on Dielectrics and Electrical Insulation. 30th Symposium on Electrical Insulating Materials (IEEE Cat. No.98TH8286), 2002
In order to investigate partial discharge (PD) degradation in composite insulating systems such as a prefabricated cable joint (PJ), we proposed an electrode system to simulate PD degradation at a solid-solid interface. It was observed that the tree at the EPR-epoxy resin interface tended to propagate into the epoxy resin bulk, even though the ...

Polymer insulator test evaluation

PowerTech Budapest 99. Abstract Records. (Cat. No.99EX376), 2003
Nonceramic insulators consist of a fiberglass core rod, metal end fittings, and weathershed housing. The weathershed homing is made of a polymeric material. Since the weathershed materials may be subject in service to degradation of aging due to harsh environmental conditions, laboratory tests are used to evaluate their performance.

Triboelectricity in insulating polymers: evidence for a mechanochemical mechanism

Faraday Discuss., 2014
Transfer of reaction products formed on the surfaces of two mutually rubbed dielectric solids makes an important if not dominating contribution to triboelectricity. New evidence in support of this statement is presented in this report, based on analytical electron microscopy coupled to electrostatic potential mapping techniques.

Polymer‐Based Nano‐Composites for Thermal Insulation

Advanced Engineering Materials, 2019
The growing need for efficient energy use prompts for effective thermally insulating materials. Nano‐composites represent an important class of materials able to fulfill these needs, enabling both sizeable energy savings and specific applications where thermal insulation has to be coupled to mechanical robustness and lightness, like in automotive and ...

Polymer insulating materials and insulators for high voltage outdoor applications

Conference Record of the 1992 IEEE International Symposium on Electrical Insulation, 2003
The authors discuss the characterization, evaluation and performance of polymer weathershed materials and insulators used for high-voltage outdoor applications. Ethylene propylene diene monomer (EPDM), ethylene propylene monomer (EPM), silicone rubber (SR), and an EPDM/silicone rubber alloy were tested.

Leveraging Insulator’s Tacticity in Semiconducting Polymer Blends

ACS Applied Materials & Interfaces
Blending conjugated polymers with insulating matrices is often utilized for engineering extrinsic properties in organic electronics. Semiconductor/insulator blends are typically processed to form a uniformly distributed network of conductive domains within the insulating matrix, marrying electronic and physical properties from individual components ...
