Lee, TS Lee, J Choi, DH Park, SY Kim, N 2024-01-21T15:14:15Z 2024-01-21T15:14:15Z 2021-09-05 1999-07 0014-3057 https://pubs.kist.re.kr/handle/201004/142084 We have investigated electro-optic properties of nonlinear optical polymer with self-crosslinkable groups in the side chain, which we synthesized previously. The system includes crosslinkable epoxy-functionalized copolymer with T-g around 120 degrees C, second harmonic coefficient as high as 45.5 pm/V at 632 mm, and with good temporal stability of the poling-induced chromophore orientation obtained by self-crosslinking reactions in the polymer matrix during the poling process. Successful strategies for simultaneous poling and self-crosslinking during the poling without addition of crosslinking agents are presented. Significant improvement in the temporal stability of chromophore orientation was accomplished up to 90%, (C) 1999 Elsevier Science Ltd. All rights reserved.
