Abstract

The paper presents new types of coloured organic-inorganic hybrids deposited as coating materials on the surface of cellulose materials by sol-gel processes. Coated materials were characterized by: XRF spectrometry, FT-IR spectrometry, UV-VIS reflectance spectra and colour measurements in CIELAB system, scanning electron microscopy (SEM), thermal analysis (TA) and dynamic mechanical analysis (DMA). Structure-properties relationships of the obtained coated cellulose materials are discussed with respect to the structure and nature of the hybrid organic-inorganic coloured coatings..
