Nanoindentation test is a useful analytical technique that can analyze the local properties of polymer composite materials or the surface properties of polymer thin films that cannot be measured by traditional mechanical property measurement methods such as tensile testers or Vickers hardness tests. The measurement principle of the nanoindentation test is to apply a load to the surface of the material to be measured using an indenter of a certain geometric shape, and to continuously measure the load and indentation depth that appear during the removal process, and to interpret the indentation-load curve obtained to measure the mechanical properties of the material. We will use Helmut Fisher's nanoindentator, the most representative testing machine for nanoindentation testing, to analyze the mechanical properties of polymer thin films coated on wafer glass. In addition, we will measure the mechanical properties of samples made under three process conditions from the analysis results, compare the mechanical properties of the three process conditions, and derive the optimal process conditions by analyzing them.
