Cellulose fibers modified by Eu3+-doped yttria-stabilized zirconia nanoparticles

Abstract

This paper describes a method for manufacturing luminescent cellulose fibers. Good optical properties of cellulose fibers under UV-C illumination were achieved by incorporating ZrO 2 (0.5 mol% of Eu 3? ) stabilized by Y 2 O 3 (7 mol%) into the fiber structure's particles. Fibers were obtained from 8 wt% cellulose solution in N-methylmorpholine N-oxide (NMMO) with the addition of a luminescent modifier in the range between 0.5 and 10 wt%. The physicochemical and mechanical parameters and the structure of these fibers were examined.

Preparing cationic cotton linter cellulose with high substitution degree by ultrasonic treatment

“…Cellulose nanocrystals have been employed as rheology and fluid loss modifiers in waterbased drilling fluids (Li, Wu, Song, Qing, & Wu, 2015). However, due to the existence of many intra-and inter-molecular hydrogen bonds in its chemical structures, cellulose is hardly soluble in most solvent systems, resulting in the limited development and utilization of its derivatives (Kulpinski, Erdman, Namyslak, & Fidelus, 2012). Chemical modification can extend cellulose's functionality, and thus broaden its application scope.…”

Luminescent cellulose fibers modified with cerium fluoride doped with terbium particles

“…Moreover, the nanocrystalline structure of Ln 3+ ‐doped compounds is advantageous and makes it possible to use the compounds in the areas where micro‐size particles materials could not be applied. Our previous studies, concerning modification of cellulose fibers by Eu 3+ ‐doped nanomaterials have proven that the morphology and size of modifiers are important factors , . They must be small enough to be introduced into fiber structure without negative effects on its mechanical properties.…”

“…Incorporation of inorganic luminescent additive is of special interest and, as has been shown in previously published papers (e.g. [16][17][18][19]), were studied in many cases.…”
