Alkoxysilane effect in hybrid material : A comparison of pHEMA-TiO2 and pMAPTMS-TiO2 nanoparticulate hybrids
May 27, 2023
We report on a comparative study of photonic sensitivities of organic-inorganic hybrids prepared
with size-selected 5nm titanium-oxo-alkoxo nanoparticles and two different organic phases:
HEMA (2-hydroxyethyl methacrylate) and MAPTMS (3-methacryloxypropyltrimethoxysilane).
After organic polymerization, the obtained pHEMA-TiO2 and pMAPTMS-TiO2 hybrids are
solids with different inter-component bindings

The structures were
mechanically more stable and easier to achieve in pMAPTMS-TiO2 compared to pHEMA-TiO2.
Moreover, higher density of the photoinduced electrons decreases the damage threshold in the
pHEMA-TiO2 hybrids.
