ANNOTATION OF MASTER’S DISSERTATION

In the framework of this dissertation work template assisted synthesis method of the nanostructured materials was investigated. This method is known as one of the low-cost and facile methods of synthesis of nanostructured materials, which allows precisely control the size of different nano-sized materials. One of the main components of this method is the template, which should have ordered, nanoscale size distriburtion and should allow to presiecely control the feature size. At the same time the template should be preapared by using low-cost and simple method. One of the materials that satisfie above requitements is the nanoporous anodic aluminum oxide matrix. This tamplate material has ordered nanosized cylindrical pores having Al₂O₃ composition. This template can be obtained by electrochemical anodic oxidation (anodization) of the aluminum plate, and allows to control the size of the pores by changing the parameters of the electrochemical process.

In the dissertation, the methods of forming such nanoporous oxide templates were studied in depth. Moreover, the effect of the parameters of the electrochemical anodic oxidation process on the size of the pores was determined experimentally. The resulting nanoporous template was successfully employed in the synthesis of copper nanowires. The morphology and the microstructures of all prepared samples were examined by using a high-precision electron microscopy and X-ray diffractometer techniques.
