The attenuated total reflection (ATR) technique is applied to study 3D ordering in the films of liquid crystalline (LC) polymers. We used a series of LC side-chain polyesters differing by the tail substitutes (NO2, OCH3 and OC4H9) in azochromophore.

In this work we study correlation between spatial molecular distributions in the contacting anisotropic polymer films and LC layers. Two kinds of side-chain azopolymers were employed: with the azochromophores containing hydrophobic OC 4 H 9 alkyl cha

The spatial orientational order of films of a series of LC polymalonates with 4-hexyloxy-4'-nitroazobenzene side groups which differ in the length of the alkylene spacer in the main chain are studied using null ellipsometry and UV/Vis spectroscopy. I

X-ray reflectivity measurements reveal anisotropy of the vertical surface roughness caused by exposure to linearly polarized UV (LPUV) light in the films of two azopolymers. The irradiated surface is found to have higher roughness in the direction pa

Fatty acids are found in many solutions treated in ultrafiltration plants, for example, in dairy products, fermentation broth, oily waste water and bleach plant effluents from pulp mills. The influence of fatty acids on the fouling of membranes is of
