Abstract
Przedmiotem wynalazku są włókna celulozowe typu lyocell modyfikowane nanomodyfikatorami typu rdzeń/powłoka, Fe3O4@SiO2/NH2/CzKo/LnF3, gdzie CzKo oznacza czynnik kompleksujący jony lantanowców znajdujące się na powierzchni nanocząstek domieszkowanych fluorków lantanowców LnF3 (gdzie Ln = La, Ce, Gd, Yb i Lu). Domieszkowane fluorki lantanowców LnF3 dodajemy w ilości od 0,1 do 0,5 mmol na 1 g Fe3O4@SiO2/NH2. Korzystnie jako czynnik kompleksujący stosuje się kwasy karboksylowe, najkorzystniej kwas poliakrylowy (PAA). Fluorki lantanowców LnF3 domieszkowane są jonami Tb3+ lub mieszaniną Gd3+, Ce3+, Eu3+.The subject of the invention are lyocell cellulose fibers modified with core / shell nanomodifiers, Fe3O4 @ SiO2 / NH2 / CzKo / LnF3, where CzKo is the lanthanide ion complexing agent located on the surface of LnF3 doped lanthanide fluoride nanoparticles (where Ln = La, Ce, Gd, Yb and Lu). The doped LnF3 lanthanide fluorides are added in an amount of 0.1 to 0.5 mmol per 1 g of Fe3O4 @ SiO2 / NH2. Preferably carboxylic acids are used as the complexing agent, most preferably polyacrylic acid (PAA). LnF3 lanthanide fluorides are doped with Tb3 + ions or with a mixture of Gd3 +, Ce3 +, Eu3 +.
