摘要

Crosslinking is one of the effective routes for improving the orientation stability of poledpolymer films. The derivative of polyvinyl alcohol containing 4-nitro-4'-alkoxystilbene andphoto-crosslinkable cinnamyl groups as side chains has been synthesized. The in-situ simul-taneous photo-crosslinking poling of synthesized polymer films has been performed. Thesecond order nonlinear optical coefficient d33 of poled film is 11 pm/V. The SHG mea-surements show that the break-over temperature of SHG signal is raised obviously after irradiation

its orientation stability is doubled as compared with that of non-crosslinking samples.

Abstract

its orientation stability is doubled as compared with that of non-crosslinking samples.
