Hydrophobicity of organic insulating materials

1988. Annual Report., Conference on Electrical Insulation and Dielectric Phenomena, 2003
The contact angle and the time for a water film to be formed on a surface are measured to investigate the hydrophobicity of UV (ultraviolet) irradiated materials. Ethylene propylene rubber and silicone rubber, both commonly used for graphic organic insulators, were adopted as specimens.

Enhancing Electrical Insulation and Thermal Conductivity in Polymer Through Constructing Energy-Dissipation Organic Electron Acceptor/Inorganic Filler.

Small
To address the issue that both electrical insulation and thermal transport performance of materials are hard to enhance synchronously, a trap-barrier synergistic strategy is proposed and utilizes the organic electronic acceptor 1,4,5,8 ...

Fluorescence quenching of organic molecule by insulator

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2013
A new kind of fluorophore 2-(4-fluorophenyl)-1-phenyl-1H-benzo[d]imidazole (FPPBI) has been synthesized and characterized by (1)H NMR, (13)C NMR, mass spectral studies and single crystal XRD. The energy transfer from FPPBI to Al2O3 nanocrystals has been studied by absorption, fluorescence and lifetime spectroscopic methods.

Ferroelectriclike dielectric response and metal-insulator transition in organic Mott insulator-gate insulator interface

Journal of Applied Physics, 2010
A ferroelectriclike dielectric response was observed in a field-effect transistor using oriented bis(ethylenedithio)tetrathiafulvalene-tetracyanoquinodimethane crystals. Phase transitions at 285 and 320 K were clearly observed in the temperature dependence of field-effect electron mobility.

Organic insulating films of nanometer thicknesses

Applied Physics Letters, 1996
It is demonstrated that monolayers of organic molecules (long chain hydrocarbons) as thin as 1.9 nm, deposited by the self-assembly technique on silicon, form high performance electrically insulating barriers. Their properties are compared with those of silicon dioxide. Leakage current densities through the organic monolayers of the order of 10−8–10−7A/

Conductor-insulator-semiconductor organic solar cells

Solar Cells, 1982
Abstract A new class of organic solar cells, conductor-insulator-semiconductor, has been developed. The novel features of these cells include the application of both a transparent conductive front electrode and a thin insulating layer in an organic solar cell.

Corona discharge within organic oil insulations

2011 IEEE International Conference on Dielectric Liquids, 2011
Presented experiment consists of laboratory testing of partial discharges activity in liquid insulating fluids. Corona discharges within different insulation fluids were measured accordingly. The trends of partial discharge main parameters are studied and described in dependence on liquid type and aging time.

Organic insulator/semiconductor heterostructure monolayer transistors

Applied Physics Letters, 2002
Field-effect transistors based on self-assembled monolayers of molecular, organic insulator/semiconductor heterostructures are demonstrated. The alkyl chains of the molecule act as the gate insulator and the π-electron moieties as the active semiconductor of the device. Mobilities up 0.05 cm2/V s and on/off ratios exceeding 105 are achieved.

Organic plastics as insulating materials

Electrical Engineering, 1943
Recent developments in new types of plastics and improved manufacturing techniques of older types are enabling these materials to assume an increasingly important role in the field of electrical insulation. Their electrical characteristics are reviewed here.
