A new orientation material for liquid crystals (LCs) based on modified ladder-like polysiloxanes (LPSs) is investigated. The curing temperature (150-200Β°C) of these grafted LPSs is much lower than that of the traditionally used polyimides (PIS) (250-300 "C). The pre-tilt angles of a nematic liquid c
