P‐76: Combined Nanostructured Layers for Display Applications

Abstract

One-step cost effective process of fabrication of a full inorganic nanostructured transparent conductive electrode and LC alignment layer has been developed. More specifically, the subject comprises a self-organized nanomesh of a valve metal, concomitant porous oxide layer with various functionality and electrochemical method of their fabrication. The nanomesh film is electrically conductive, optically transparent and flexible. It can be fabricated on a variety of substrates, including flexible and rigid substrates. High effective LC alignment layers based of nanostructured alumina can be fabricated at the same anodization process by special electro-chemical technique in sulfuric and oxalic acids to form a self ordered nanoporous structure of alumina which has a "vertical" surface area that prevails over the "horizontal" one even though Al film's thickness is small. The possibility to control distances between pores and their sizes during the process of anodizing/etching enables to optimize alignment surface according to the required LC material.

“…The electrochemical anodization technique of inorganic films on a glass substrate, which provide simultaneously a high optical transparency and good alignment properties for LC molecules on the substrate surface, is one of the promising solutions for the design and production of next generation of displays . At the same time, different reaction possibilities for the functional groups and the cyclic fragments of the corresponding substituted cyclohexenones, isoxazolines, and similar to them intermediates allow transformations to be achieved selectively and give a chance of preparing anisotropic compounds and materials with novel combinations of the structural fragments of molecules .…”

“…It has been reported that the alkanoylcyclohex-2-enones, alkanoylcyclohexanones, and similar to them diketones are promising intermediates for the preparation of various liquid crystalline compounds [1][2][3]. Additionally, we presented novel approach to fabrication of fast switching VA LCDs [4,5]. The electrochemical anodization technique of aluminum films on a glass substrate, which provide simultaneously a high optical transparency, a low electrical resistivity of the work substrate, and good alignment properties for LC molecules on the substrate surface, is one of the promising solutions for the design and production of next generations of displays.…”

Paper No P19: Aluminum Nanostructured Coatings as Alternatives to Metal Oxide and Transparent Semiconductors

“…The novel low‐temperature nonlithography method of transparent conductive electrodes fabrication will be discussed. The electrochemical anodization/etching of aluminum film is a key component for this method . It allows fabricating a self ordering aluminum transparent electrode with 70–80% average transmission in the visible range and 10–20 Ω/A sheet resistance .…”
