Popis: A study was carried out on the preparation and properties of film materials obtained from hydroxyethylcellulose filled with micro- and nanocrystalline cellulose, which may hold promise for use as nonpolluting biodegradable coatings or films. We studied the effect of size (micro- or nanocrystalline cellulose), means of dispersion (mechanical stirring or ultrasonic treatment), and filler concentration on the deformation-strength properties of filled hydroxyethylcellulose films. The effect of the means of dispersion on the structure and properties of the matrix derived from two different types of hydroxyethylcellulose and on the efficiency of dispersion of the filler was studied by viscosimetry, UV spectrophotometry, and optical microscopy. Independently of the type of hydroxyethylcellulose, ultrasonic treatments leads to a reduction in the viscosity of their solutions and increase in optical transparency but the effect of such treatment has significantly different effects on the deformationstrength properties of both unfilled films and the films filled with micro- and nanocrystalline cellulose.
