Compatibility Studies of Some Azo Polymer Blends

摘要

Azo polymers have many special properties. In the search for new materials foroptical applications, such as reversible optical storage and nonlinear optical devices, azo polymers have attracted much attention. Polymers with low azo concentrations are particulary useful. The writing and erasing efficiency depends on the energy input from the irradiation light during the process. In principle, lower energies would be required to induce local variations of optical properties in polymers with low azo concentrations.
