For dope-modified fibers, we hypothesize that cellulose chains act as seeds for directed silica NP self-assembly. This results for D SiO 2 in discrete micron-sized rods, homogeneously distributed throughout the fiber and for glycidoxy-surface modified D SiO 2 @GLYEO in nano-sized surface aggregates and a cross-sectional core-shell fiber morphology.
