Abstract

A method for producing metamaterial cross-linked polyvinyl alcohol–magnetite nanoparticles based on the chemical deposition of Fe₃O₄ ions with NH₃ solution into the volume of polymer granules is considered. The granules of the metamaterial are used as a sensor element for determining the composition of solutions by optical micrometry: the kinetic dependences of the swelling of the granules in solutions of aliphatic acids and their sodium salts and sugars are studied. The doping of the polymer with Fe₃O₄ particles increases the measurement accuracy at the initial part of the kinetic curve.

用于光学显微测量的粒状超材料交联聚乙烯醇-磁铁矿

摘要

考虑了一种基于 Fe ₃ O ₄离子与 NH ₃溶液化学沉积到聚合物颗粒体积中的超材料交联聚乙烯醇-磁铁矿纳米颗粒的生产方法。超材料的颗粒用作传感器元件，用于通过光学显微法确定溶液的组成：研究了颗粒在脂肪酸及其钠盐和糖溶液中溶胀的动力学依赖性。用 Fe ₃ O ₄颗粒掺杂聚合物提高了动力学曲线初始部分的测量精度。
