Abstract
In this work, the study of copolymer acrylic films was carried out on a laser photoelectric ellipsometer LEF-ZM-1. In this work, we consider a chemical sensor based on an integrated optical sensing element, propose structural schemes of IOCS, as well as conduct studies on a simulation model and assess the potential for detecting changes in the concentration of various substances. For this, in the course of the work, we studied the change in the refractive indices of polymer films with a Navbahor bentonite content of 5 wt.%, Depending on the time of their swelling in aqueous solutions containing Cr ions. The most important characteristics for acrylic copolymers are mechanical strength and sorption, since it is the values of these parameters that impose significant restrictions on the field of their application. Therefore, in this article, in addition to ellipsometry, the effect of the initiator concentration on the absorption properties of polymer composites and the influence of the synthesis temperature on the absorption properties of copolymer composites containing Navbahor bentonite are also studied. During the study, it was clarified that acrylic mineral-containing composites obtained at 42°C have the maximum sorption ability.
