摘要：

DPPC-based phospholipid model membranes with lyotropic lamellar structure and thermotropic liquid crystals of several chemical classes were loaded with particles of laponite (untreated, organomodified and acid-modified). DSC thermograms showed distinct difference between membranotropic action of the three types of laponite, which was related to peculiar interaction features on the molecular level. The general trends were qualitatively similar in thermotropic liquid crystals, evidenced by temperature-dependent optical transmission and polarizing optical microscopy.
