We have performed SANS studies on a liquid crystal (LC) composite system where 0.5-3% of hydrophobic SiO2 particles were dispersed. The Bragg reflections from the smectic structure show that the layer alignment is perfect after cooling the system in a field of H = 1.2 T. This alignment is memorised (after heating-cooling at H = O) proving the aligning ability of the dispersed particles on the LC layers. We assume that the silica particles form loosely connected porous aggregates.
