US Patent 7781556 Lyotropic liquid crystals and vesicles

Silicone based liquid crystal and vesicles are prepared by first reacting (A) an ≡Si—H containing polysiloxane, (B) a mono-alkenyl polyether, in the presence of a platinum catalyst until an ≡Si—H containing polysiloxane with polyether groups (C) is formed. The ≡Si—H containing polysiloxane with polyether groups (C) is then reacted with (D) an unsaturated hydrocarbon such as an α,ω-dienes, and (E) water, in the presence of a platinum catalyst until the silicone based liquid crystal or vesicle is formed. The silicone based liquid crystal or vesicle can also be heated until a hard liquid crystal gel or vesicle paste are formed.
