Multifunctional liquid crystalline photoreactive polymers for polarization holography |
| abstract |
A multifunctional liquid crystalline photoreactive polymer in which at least some of the polymer side-chains have an ultraviolet photoreactive moiety and at least some of the polymer side-chains have a calamitic mesogenic moiety are provided. At least some of the polymer side-chains have a photo-curable moiety a thermal-curable moiety. In some embodiments, the polymer is in the form of a co-polymer. In some embodiments, the polymer is in the form of a ter-polymer. The polymer is used in applications that require stable birefringement films. Such films are produced from the polymer by subjecting the polymer to ultra-violet light to cause side-chain cross-linking thereby inducing anisotropy. The anisotropy is then amplified by exposing the polymer to an elevated temperature. |
