abstract = {Scanning electron microscopy, ultra-small-angle neutron
scattering (USANS), small-angle neutron and X-ray scattering
(SANS and SAXS), as well as low-temperature nitrogen
adsorption, were used in the studies of micro- and
mesostructure of polymer matrix prepared from air-dry
preliminarily disintegrated cellulose nano-gel film
(synthesized by Gluconacetobacter xylinus) and the
composites based on this bacterial cellulose. The composites
included ZrO2 nanoparticles, Tb3+ in the form of low
molecular weight salt and of metal-polymer complex with
poly(vinylpyrrolydone)-poly(methacryloyl-o-aminobenzoic
acid) copolymer. The combined analysis of the data obtained
allowed revealing three levels of fractal organization in
mesostructure of G. xylinus cellulose and its composites. It
was shown that both the composition and an aggregation state
of dopants have a significant impact on the structural
characteristics of the organic-inorganic composites. The
composites containing Tb3+ ions demonstrate efficient
luminescence; its intensity is an order of magnitude higher
in the case of the composites with the metal-polymer
complex. It was found that there is the optimal content of
ZrO2 nanoparticles in composites resulting in increased Tb3+
luminescence.},
