Nano insulation materials

Research is also ongoing to develop new high-performance thermal insulation materials, for example, nano insulation materials (NIM) [31,69,70,103-114] that utilize the Knudsen effect to achieve their low thermal conductivity without applying a vacuum in the pores. One possible pathway toward NlMs is to...

Single-walled carbon nanotubes are known to possess extraordinary strength.138 Mechanical properties of BN nanotubes would be worthy of exploration. Unlike carbon nanotubes, BN nanotubes are predicted to have stable insulating properties independent of their structure and morphology. Thus, BN tubes can be used as nano-insulating devices for encapsulating conducting materials like metallic wires. Filled BN nanotubes are expected to be useful in nanoscale electronic devices and for the preparation of nano-structured ceramics. 

Polymer nanocomposite materials as a new insulation material also have been given attention because the properties of the original material can be drastically improved by adding a few percent of nano-sized filler. Polymer nanocomposites for HV insulation have been extensively being studied in recent years because of their unique properties and ability to enhance electrical performance. The analysis result showed that DC conductivity exhibits...

Micro- (and even nano-) electrode arrays are commonly produced with photolithography and electronic beam techniques by insulating of macro-electrode surface with subsequent drilling micro-holes in an insulating layer [136, 137], Physical methods are, however, expensive and, besides that, unsuitable for sensor development in certain cases (for instance, for modification of the lateral surface of needle electrodes). That s why an increasing interest is being applied to chemical approaches of material nanostructuring on solid supports [140, 141],... 

Nano-electrode arrays can be formed through nano-structuring of the electrocatalyst on an inert electrode support. Indeed, if the current of the analyte reduction (oxidation) on a blank electrode is negligible compared to the activity of the electrocatalyst, the former can be considered as an insulator surface. Hence, for the synthesis of nanoelectrode arrays one has to carry out material nano-structuring. Recently, an elegant approach [140] for the electrosynthesis of mesoporous nano-structured surfaces by depositioning different metals (Pt, Pd, Co, Sn) through lyotropic liquid crystalline phases has been proposed [141-143],...
