摘要
以二乙酸纤维素为基础聚合物,三羟甲基三聚氰胺(TMM)或六羟甲基三聚氰胺(HMM)为交联剂,制得含正离子生色团的二阶非线性光学聚合物.结果表明,以HMM为交联剂制得的非线性光学聚合物的驰豫行为强于采用TMM者,这与小分子物质的存在及HMM的自缩合能力较强有关.
A new type of second order nonlinear optic polymer based on the natural macromolecular cellulose diacetate and the cationic chromophore 1,3-dimethyl-2- （4′-N, N- dimethyl- aminophenyl ）-azo-imidazole chloride was prepared. The crosslinking agent was trimethylolmelamine （ TMM ） or hexamethylolmelamine（HMM）. The polymer film, resulted from drying the solution of the mixture composed of cellulose diacetate, chromophore and TMM or HMM in dimethyl formamide was subjected to curing and corona poling at the same time to make the polymer form crosslinking network and the chromophore orient. Fig 1 is the temperature dependence of lg （tan δ）of the cured sample containing TMM or HMM,respectively.
