Abstract

Abstract Novel superabsorbent polymers (SAPs) were created by solution polymerization at ambient temperature using potassium polyacrylate (KPA), polyvinyl alcohol (PVA), and magnesium chloride as a cross-linking agent with different weights of 0.4, 0.5, 0.6, 0.7, 0.8, and 1 g for KPA and 0.33, 0.44, 0.55, 0.733, and 1.1 g for PVA. Fourier transforms infrared (FTIR) and UV-Vis spectroscopy were used to determine the chemical composition of the SAP complexes. The outcomes revealed that the KPA and PVA successfully interacted with the magnesium chloride. The morphology of the surfaces shows a uniform porous interconnected microstructure as revealed by field emission scanning electron microscopy. The effective preparation was confirmed by thermal characterization (thermogravimetric analysis and differential scanning calorimetry) of the SAPs. The influence of the cross-linker agent on the SAPs’ water absorbency was examined. The magnesium polyacrylate (Mg-PA) (0.6 g of MgCl2) SAP has a maximum swelling capacity of 650%, while that of magnesium polyvinyl alcohol (Mg-PVA) (0.55 g of MgCl2) was 244%. The findings confirmed that the SAPs have excellent swelling and water-retaining capabilities. The strategy used in this investigation may function as a model for developing and widespread usage of SAPs in agriculture and horticulture.

聚丙烯酸酯-聚乙烯醇镁配合物的合成、研究及其在高吸水性聚合物中的应用

摘要以聚丙烯酸钾(KPA)、聚乙烯醇(PVA)和氯化镁为交联剂，分别为0.4、0.5、0.6、0.7、0.8和1 g, PVA为0.33、0.44、0.55、0.733和1.1 g，在常温下通过溶液聚合制备了新型高吸水性聚合物(sap)。傅里叶变换红外光谱(FTIR)和紫外可见光谱(UV-Vis)测定了SAP配合物的化学成分。结果表明，KPA和PVA成功地与氯化镁相互作用。在场发射扫描电镜下，表面形貌显示出均匀的多孔互联微观结构。通过热表征(热重分析和差示扫描量热法)证实了该制备方法的有效性。考察了交联剂对sap吸水性能的影响。聚丙烯酸镁(Mg-PA) (0.6 g MgCl2) SAP的最大溶胀量为650%，而聚乙烯醇镁(Mg-PVA) (0.55 g MgCl2)的最大溶胀量为244%。研究结果证实，sap具有优异的膨胀和保水性。本研究中使用的策略可以作为开发和广泛使用sap在农业和园艺中的模型。

期刊介绍： The journal focuses on the micromechanics and nanomechanics of materials, the relationship between structure and mechanical properties, material instabilities and fracture, as well as size effects and length/time scale transitions. Articles on cutting edge theory, simulations and experiments – used as tools for revealing novel material properties and designing new devices for structural, thermo-chemo-mechanical, and opto-electro-mechanical applications – are encouraged. Synthesis/processing and related traditional mechanics/materials science themes are not within the scope of JMBM. The Editorial Board also organizes topical issues on emerging areas by invitation. Topics Metals and Alloys Ceramics and Glasses Soils and Geomaterials Concrete and Cementitious Materials Polymers and Composites Wood and Paper Elastomers and Biomaterials Liquid Crystals and Suspensions Electromagnetic and Optoelectronic Materials High-energy Density Storage Materials Monument Restoration and Cultural Heritage Preservation Materials Nanomaterials Complex and Emerging Materials.
