Abstract: The extensive application in future of nano webs has attracted world tendency toward them. The identification of nano webs| characteristics can direct consumer toward their end uses. Many nano web characteristics depend on its structure. Since they are made of nano fibres and have thin structure, conventional optical techniques are not completely applicable to measure their structural properties. This paper will discuss the development of image analysis algorithms to measure and evaluate structural and morphological characteristics of nano web images including fibre properties (such as fibre orientation distribution, fibre diameter), pore properties (such as pore size and shapes) and web properties (such as web uniformity and fibre intersections). The results show that the method is capable of characterising real nano coated webs.

Keywords: nano coated webs; image analysis; nanocoatings; nanotechnology; image processing; nanowebs; fibre orientation distribution; fibre diameter; pore size; pore shapes; web uniformity; fibre intersections.
