| titleOfInvention | Method of producing a liquid crystal material that reflects more than 50% of non-polarised incident light |
| abstract | The invention relates to a method of producing a liquid crystal material. The inventive method is characterised in that it comprises the following steps consisting in: applying a first treatment to a liquid crystal mixture having a helical structure comprising a first non-photoreactive liquid crystal (A) and a second photoreactive liquid crystal (B), said first treatment modifying a handedness of the helix of the mixture; and applying a second treatment to the mixture such that the second liquid crystal (B) forms a polymer network, said second treatment being performed during all or part of the first treatment such that the liquid crystal material retains a memory of the modifications to the helix and the entire volume of the material has both a right-handed and left-handed helical structure. The invention also relates to a liquid crystal device comprising a liquid crystal material consisting of at least one liquid crystal having a helical structure, which is characterised in that the entire volume of the material has both a right-handed and left-handed helical structure, such that the device has a reflection rate of more than 50%. |
