Stabilization of soft systems exhibiting self-organization behaviour remains a highlighted task. New smart nanocomposite system has been designed by filling of a stretched porous polyethylene film by chiral ferroelectric liquid crystal possessing polar self-assembling behaviour. Lactic acid derivative exhibiting the paraelectric orthogonal and the ferroelectric tilted smectic phases over a broad temperature range was used as a self-assembling material. The morphology of the nanocomposite film is checked by AFM. Properties of nanocomposite are studied by POM, DSC, SAXS, WAXS and broadband dielectric spectroscopy. The effect of porous polyethylene confinement on self-assembling, structural and dielectric behaviour of chiral LC is established and discussed. While the mesomorphic and structural properties of the nanocomposite were not much affected in comparison to that of a pure liquid crystalline material, the polar properties have been toughly suppressed by the specific confinement.
