摘要
提出了一种制备纳米矿物包埋纳米复合水凝胶的新方法。以丙烯酰胺和丙烯酸为共聚物，在Cd2+ та S2-结构形成离子扩散通量的条件下，在水凝胶基质中原位合成了CdS纳米颗粒。通过XRD、能谱分析、紫外光谱等方法证实了CdS纳米颗粒在聚合物基体中的形成。研究了聚合物基质含量对水凝胶物理力学性能的影响。
Formation and properties of cross-linked polyacrylamide hydrogels with cds nanoparticles
The new method of obtaining nanocomposite hydrogels with embedded mineral nanoparticles has been proposed. CdS nanoparticles have been synthesized in situ in hydrogel matrix based on the copolymer of acrylamide and acrylic acid under the conditions of diffusion fluxes of Cd2+ та S2- structure-forming ions. The formation of CdS nanoparticles in polymeric matrix has been approved by the methods of XRD, energy- dispersive analysis, UV-spectroscopy. The influence of the content of polymer matrix onto physico- mechanical properties of hydrogel has been studied.
