The effect of alcohol- and amino-functional compatibilizers in nanocomposites of organic–inorganic (O–I) matrices with layered nanofillers (LN) was studied. The alcohol-functional compatibilizers are shown to have a marked influence on morphology, surface- and mechanical properties of the coatings prepared, in spite of the very small amount of both filler and compatibilizer (together 0.5 wt%). The studied O–I matrices were polyepoxy-functional polysiloxanes cured with organic diamines. Two commercial clays were used as LN in the concentration of 0.5 wt%: natural montmorillonite (Cloisite Na, abbreviated MNa) and Bentonite for water systems (BW). These clays were compatibilized by three hydroxylcontaining substances: Polyethylene glycol 4000, TWEEN 80, and tris(hydroxymethyl)aminomethane (TRIS).
