Side-chain liquid-crystalline polyesters for optical information storage.
We report erasable holographic recording with a resolution of at least 2500 lines/mm on unoriented films of sidechain liquid-crystalline polyesters. Recording energies of approximately 1 J/cm(2) have been used. We have obtained a diffraction efficiency of approximately 30% with polarization recording of holograms. The holograms can be erased by heating them to approximately 80 degrees C for app...
متن کاملAzobenzene Side-Chain Liquid Crystalline Polyesters with Outstanding Optical Storage Properties
A flexible azobenzene side-chain liquid crystalline (SCLC) polyester architecture employed for reversible optical storage is described. The modular design allows four structural parameters to be individually modified. These parameters: ithe methylene side-chain spacer length, iithe substituent on azobenzene, iiithe methylene main-chain segment length, and ivthe polyester molecular mass, all inf...
متن کاملStilbene-containing Thermotropic Liquid Crystalline Polyesters for Aerospace Applications
Materials used in space travel must maintain thermal and dimensional stability in extreme conditions, while remaining melt processable for ease of industrial production. The rigid chemical structure of stilbene often correlates to polymers exhibiting a liquid crystalline morphology and the olefinic bond undergoes a [2 + 2] cycloaddition in the presence of UV light. Based on the combined benefit...
