Scientific problem:
Polymer coatings are a class of surface coatings consisting of macromolecules attached to a solid surface. They have been widely studied in recent years due to their practical applications such as lubricants, smart coatings, protective coatings. Specific polymer passivation for macromolecule adsorption is of current research interest. Several grafting and coating techniques are considered for these goals. They are different in approaches with varying density and structure of polymer layers, including undesirable (in final use) components used in the synthesis. Often, a complex synthesis mechanism for this technique results in a lack of understanding of the final structure of polymer coaitings, as well as their evolution when using in various temperature and humidity conditions. It requires a detailed investigation of the structure of polymer coatings, especially when they are exposed to specified conditions and can be studied only using penetrating radiation beams such as neutron radiation.
Objective:
Investigation of the polymer coating density over the interface depth using specular neutron reflectometry. Research of the elongation of polymer chains in different environments.
Comparison of the data obtained for polymer coatings in dry and 'wet' states.
Tasks:
1. Description of special polymer layers using XRR and neutron reflectometry in dry conditions. Estimation of layer density and roughness.
2. Evolution of polymer layers including possible swelling in 'wet' conditions using neutron reflectometry.
