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.

羟乙基纤维素薄膜填充微细和纳米晶纤维素的形变强度特性

对由填充了微晶和纳米晶纤维素的羟乙基纤维素制得的薄膜材料的制备和性能进行了研究，这有望用作无污染的可生物降解涂料或薄膜。我们研究了尺寸（微晶或纳米晶纤维素），分散方式（机械搅拌或超声处理）以及填料浓度对填充的羟乙基纤维素膜变形强度性能的影响。通过粘度法，紫外分光光度法和光学显微镜研究了分散方式对衍生自两种不同类型羟乙基纤维素的基质的结构和性能以及填料分散效率的影响。与羟乙基纤维素的类型无关，
