Abstract:
1. A method for recycling liquid crystal, the method comprising: receiving a liquid crystal mixture; conducting at least one separation process to separate a first liquid crystal group from the liquid crystal mixture, wherein the first liquid crystal group is separated from the liquid crystal mixture based on at least one physical characteristic chosen from flow viscosity (η), dielectric anisotropy (Δ∈), birefringence (Δn), clearing point (T conducting at least one additional separation process to separate a second liquid crystal group from the remaining of the liquid crystal mixture, wherein the second liquid crystal group is separated from the remaining of the liquid crystal mixture based on at least one physical characteristic chosen from flow viscosity (η), dielectric anisotropy (Δ∈), birefringence (Δn), clearing point (T forming a reformulated liquid crystal mixture using the first liquid crystal group and the second liquid crystal group.
