Mechanism and Model of Laser-Driven Mass Transport in Thin Films of Azo Polymers

Abstract

Samples of poly 4'-(2-(ACRYLOYLOXY)ETHYLethylamino-4-nitroazobenzene were used to inscribe surface gratings by optical means, and the Navier-Stokes theory of flow under an applied pressure was used to model the process. Dependence on molecular weight, light intensity, quantum yields of photoisomerization, chromophore free volume, film thickness and bulk modules was established.
