Summary Thermotropic liquid crystalline polymer (TLCP) nanocomposites with different organoclay contents were prepared by a method combining ultrasonication, centrifugation and solution casting methods. The effects of organoclay concentration on morphology, liquid crystallinity and thermal properties of nanocomposites were characterized. Molecular level interactions existed in nanocomposites. With a small amount of organoclay (nominal 3.0 wt %), it was enough to change TLCP properties with enhanced thermal stability though with a small negative effect on liquid crystallinity. When high concentration organoclay was added, thermal stability decreased and liquid crystallinity lost with shear-induced phase separation occurrence.
