The study's aim was to synthesize a crystalline film formed by L‐threonine crystals complexed with Cu2+ ions (LTCu) dispersed in a galactomannan (Gal) solution as well as to characterize its structural, vibrational, and thermal properties. Gal(LTCu) films were prepared by the addition of copper II L‐threoninate crystals in concentrations of 0.25, 0.50, and 0.75 in 2% Gal solution. To characterize the Gal(LTCu) properties, we used X‐ray diffraction (XRD), UV–Vis and Raman spectroscopy, thermogravimetry, and thermal analyses (TG‐DTA). XRD showed that the Gal(LTCu) films are crystalline and have acquired coloration similar to the one of LTCu crystal. The UV–Vis spectra revealed that the films tend to assume a square planar conformation due to Jahn Teller effect. Bands related to the interaction between the metal ion with the organic compounds were observed through the Raman spectra. TG‐DTA showed that the films exhibit low thermal stability due to the dehydration process. POLYM. ENG. SCI., 60:71–77, 2020. © 2019 Society of Plastics Engineers

L-苏氨酸与铜（II）络合的结晶膜分散在半乳甘露聚糖溶液中：结构，振动和热研究
这项研究的目的是合成由L-苏氨酸晶体与Cu 2+络合形成的结晶膜。离子（LTCu）分散在半乳甘露聚糖（Gal）溶液中，并表征其结构，振动和热性能。通过在2％Gal溶液中添加0.25、0.50和0.75浓度的L-苏氨酸铜II晶体来制备Gal（LTCu）膜。为了表征Gal（LTCu）特性，我们使用了X射线衍射（XRD），UV-Vis和拉曼光谱，热重分析和热分析（TG-DTA）。X射线衍射表明，Gal（LTCu）薄膜为晶体，并具有与LTCu晶体相似的着色。UV-Vis光谱显示，由于Jahn Teller效应，这些薄膜倾向于呈现正方形平面构象。通过拉曼光谱观察到与金属离子与有机化合物之间的相互作用有关的带。TG-DTA表明，由于脱水过程，这些膜表现出较低的热稳定性。POLYM。ENG。SCI。，60：71–77，2020.©2019塑料工程师协会
