Abstract

In order to prevent the spread of counterfeit and shoddy products, fluorescent fibers from inorganic fluorescent substance and organic materials are continuously being developed. In this paper, a novel method, which was different from spinning method, was presented for preparing fluorescent cellulose fiber (FCF). This method involved modification of cellulose fiber by sodium chloroacetate and self-assembly of cellulose and Eu³⁺ by coordination interaction. The fluorescence properties, crystallinity, element compositions and microscopic morphology of the fluorescent cellulose fiber were characterized. The preparation mechanism of fluorescent cellulose fiber was explained. The red was presented by the FCF when it was exposed under the ultraviolet at wavelength of 397 nm, which showed its potential application in the field of security. The self-assembled preparation method was expected to be a novel candidate for the preparation of cellulose-based fluorescent fibers.

荧光纤维素纤维的新型制备方法和表征

摘要

为了防止假冒伪劣产品的扩散，来自无机荧光物质和有机材料的荧光纤维正在不断开发中。本文提出了一种不同于纺丝法的新方法来制备荧光纤维素纤维（FCF）。该方法包括用氯乙酸钠修饰纤维素纤维，以及纤维素和Eu ^3+的自组装。通过协调互动。表征了荧光纤维素纤维的荧光性质，结晶度，元素组成和微观形态。说明了荧光纤维素纤维的制备机理。FCF在397 nm波长的紫外线下暴露时呈现红色，这表明它在安全领域具有潜在的应用。自组装的制备方法有望成为制备基于纤维素的荧光纤维的新选择。
