The title of our research is Modification of Inorganic Oxides with Poly(hydridomethylsiloxane)s as an Approach to Mixed Functional Surfaces. The purpose of doing this research is to provide insight in controlling the surface properties of inorganic oxides as it has profound impacts on anti-fouling, adhesion, and other applications. Our goal is to analyze and interpret the data collected from contact angles and ellipsometry. Some objectives for this research endeavor is to progress towards publishing a paper that builds on previous work done with hydridomethylsiloxanes (HMS). Along with this, we would be able to publicly speak about our findings with other scientists interested with similar research.

We expect to learn more about different surface properties via an interfacial hydrosilylation reaction and how it further affects contact angle hysteresis. The chemical molecule used factors in heavily when thinking about the expected outcomes. Some known factors can be based on overall structure and molecular polarity. Additionally, our research team is planning to visit Amherst University to receive more specific data on our samples like x-ray photoelectron spectra. The main methods that will be applied throughout this research is ellipsometry and goniometry. The purpose of ellipsometry is to verify if the reaction took place. This is seen as the thickness of these samples increase. Goniometry looks at the angles made by adding or removing water on the surface. The hysteresis is analyzed by subtracting the advancing contact angle from the receding contact angle. This tells us how homogeneous or uniform the surface of our samples are. A high hysteresis value is indicative of a surface that is not homogeneous and a low hysteresis value means that the surface is rather homogeneous.
