Study of the Surface Structure of Membranes and Correlation Analysis with the Conformational State of the Polymer
Загрузки
The paper presents a topographic study of the surface relief of the solidified phase of polymer composite membranes using scanning probe microscopy. The study was conducted using a high-resolution scanning probe and tunneling microscope, Certus Standart V, equipped with an NSG20-type cantilever, operating in non-contact mode. Tips with of radius of probe of 10 nm, 5 nm, 3 nm, 2 nm, and 1 nm were used, enabling nanoscale structural analysis.
Reducing the radius of the probe tip resulted in a consistent increase in spatial resolution, making it possible to perform detailed nanoscale structural characterization and to identify structural elements of different sizes and shapes. A correlation was identified between the conformational state of the polymer and the structural characteristics of the solidified phase. It was found that decreasing radius of probe enhances spatial resolution, which allows for more precise identification of nanostructural elements and inhomogeneities (heterogeneity).
