Abstract

We present the first small angle neutron scattering studies on liquid crystal polymer composite systems, where small amounts of polymers are dispersed in liquid crystals. A recent study (A. Jákli, D. R. Kim, L. C. Chien and A. Saupe, 1992, Appl. Phys. 72, 3161) showed that even 1 wt% of polymer can induce phase separation in the form of fibres. We have found that the cross-sectional radius of such fibres is typically 300 A and they have rough surfaces. The spatial distribution of the fibres does not change during the phase transitions of the liquid crystal. We have found that there is a correlation between the size of the separated polymer particles and the roughness of their surfaces: larger objects have less smooth surfaces.
