摘要

比较了聚苯乙烯(PS)、聚甲基丙烯酸甲酯(PMMA)、聚苯乙烯(PS)/聚甲基丙烯酸甲酯(PMMA)共混物和金属离子中心配合物制备的复合薄膜的性能。以L(4-羟基- n -[2-[(4-羟基苯甲酰)氨基]乙基]苯酰胺为配体，与乙二胺缩合制备了Cr(III)、Co(II)、Ni(II)、Cu(II)等新型配合物。采用LC-MS、1H-NMR、FTIR、UV-Vis和XRD对配体和配合物进行结构分析。测量了新型配合物的电导率和磁化率。通过扫描电镜(SEM)和原子力显微镜(AFM)对透明膜的形貌进行了表征，通过热重分析仪(TGA)对其热稳定性进行了表征，通过折射仪对其光学性质进行了表征。通过对PS、PMMA和PS/PMMA共混物进行新型配合物改性，获得了热稳定、透明、可折叠、具有永久颜色的复合膜。

Preparation and characterization of novel transparent and foldable polymers modified with Cr(III), Co(II), Ni(II), and Cu(II) complexes

The properties of films prepared from polystyrene (PS), poly(methyl methacrylate) (PMMA), and polystyrene (PS)/poly(methyl methacrylate) (PMMA) blends and composite films prepared with metal ion-centered complexes were compared. New complexes of Cr(III), Co(II), Ni(II), and Cu(II) prepared according to the template were synthesized from ligand L (4-hydroxy-N-[2-[(4-hydroxybenzoyl)amino]ethyl]benzamide) prepared by condensation of 4-hydroxybenzoic acid and ethylenediamine. Structural analysis of ligands and complexes were determined by LC-MS, ¹H-NMR, FTIR, UV-Vis, and XRD. The conductivities and magnetic susceptibility of novel complexes were measured. Morphological properties of the transparent films by SEM and AFM, their thermal stabilities by TGA, and their optical properties by refractometry were characterized. Original composite films of PS, PMMA, and PS/PMMA blend modified with novel complexes were obtained as thermally stable, transparent, and foldable composite films with permanent colors.

期刊介绍： The scope of the journal is to publish original contributions and reviews on studies, methodologies, instrumentation, and applications involving the analysis and characterization of polymers and polymeric-based materials, including synthetic polymers, blends, composites, fibers, coatings, supramolecular structures, polysaccharides, and biopolymers. The Journal will accept papers and review articles on the following topics and research areas involving fundamental and applied studies of polymer analysis and characterization: Characterization and analysis of new and existing polymers and polymeric-based materials. Design and evaluation of analytical instrumentation and physical testing equipment. Determination of molecular weight, size, conformation, branching, cross-linking, chemical structure, and sequence distribution. Using separation, spectroscopic, and scattering techniques. Surface characterization of polymeric materials. Measurement of solution and bulk properties and behavior of polymers. Studies involving structure-property-processing relationships, and polymer aging. Analysis of oligomeric materials. Analysis of polymer additives and decomposition products.
