Absorption Studies of Optically Nonlinear Side-Chain Polymer and Polymer-Dye Films oriented by Corona Poling
- 25 Downloads
Spectroscopic absorption measurements in the wavelength range from 700 to 300 nm are used to study the orientation of optically nonlinear side-chain groups in an acrylic polymer and dye guest molecules in a polymer matrix by corona poling process. The time stability and the annealing behaviour of these films are measured. The poling process produces efficient orientational order at room temperature of the acrylic side-chain polymers. With stepwise annealing up to poling conditions the orientation order was measured. The guest-host systems show a different behaviour.
