Abstract

Ferroelectric liquid crystal (LC) polymers have several advantages compared to low molecular weight ferroelectric LCs (as well as a few disadvantages). The synthesis, characterization, and physical properties of a ferroelectric LC homopolymer and a related new ferroelectric LC polymer system—consisting of a block copolymer with microdomain morphology—are reported. The nearly total absence of hysteresis indicates that the system is monostable, which could make such polymers suitable for display applications with active matrix addressing.
