摘要

Preparation of second order nonlinear optic (NLO) materials based on cellulose diacetate and melamine derivatives was tried. The NLO chromophore sodium [4'-(N, N-dihydroxyethyl) amino] phenyl-4-azo-benzene sulfonate incorporated into the crosslinking network resulted from cellulose diacetate and trimethylolmelamine or hexamethylolmelamine. The poled and cured NLO materials exhibited the electrooptic coefficient r 13 of 1.72 pm/V or 1.15 pm/V at the laser wavelength of 1550 nm, modulation frequency of 12.7 kHz, and the r 13 value decreased to 71.5% or 81.5% of the initial values after 4 days. The laser transmission loss was 0.94 dB or 1.76 dB. The crosslinking materials showed better temporal stability than the material of the host/guest type. The results of FTIR, dielectric relaxation, and TGA proved the formation of the crosslinking structure and that the dielectric relaxation was suppressed by higher crosslinking density.
