Abstract
The Langmuir-Blodgett technique has been applied to build optically homogeneous monolayer films of multi-wall carbon nanotubes (MWNTs) which possess good surface spreading properties at the air/water interface. Mono-layers of MWCNTs- arahidic acid were deposited on glass substrates with ITO contacts by vertical lifting. Prepared substrates used to make liquid crystals optical cells to detecting morphology of MWCNT mono-layers which play the aligning coveting role. We demonstrate that MWCNT aligned by one direction in the Langmuir-Blodgett film which was transferred on the substrate with keeping MWCNTs aligning.
