Effect of biocidal additives on the mesostructure of epoxy-siloxane bioactive coatings

Popis výsledku v původním jazyce

We investigate the structure formation of sol–gel synthesized epoxy–siloxane compositions with a ratio of the main precursors of R TEOS/EPONEX 1510 = 27/27 wt %, modified with biocidal additives of detonation nanodiamonds (c DND = 0.13, 0.27, and 0.58 wt %), titanium dioxide ( c TiO 2 = 0.1, 0.3, and 0.5 wt %), and Photosens (c Ph = 0.04, 0.1, and 0.27 wt %), by small-angle X-ray scattering. Based on small-angle X-ray scattering (SAXS) data, it is revealed that the synthesized epoxy–siloxane xerogels are systems with a twolevel fractal structure, in the formation of which the siloxane component plays the dominant role. It is found that the introduction of small additions of detonation synthesis, titanium dioxide, or Photosens (less than 1 wt %) into the epoxy–siloxane compositions affects both the fractal dimension D S of the surface and the size d c1 of primary particles, and the fractal dimension D M and sizes d c2 of mass fractal clusters formed from them.
