Description
Summary:•Two eco-friendly nanocoatings were prepared containing titanium dioxide nanoparticles incorporated by two different methods.•Spectroscopic investigations were conducted to verify the inorganic constituents.•Substrate independent and traditional nanoindentation analysis were conducted on nanocoatings.•Surface morphology varied with the variation in inorganic constituent.•Failure mechanism was predicted and verified using microscopic techniques. The eco-friendly (green) silicone nanocoating compositions containing titanium nanoparticles were developed and tested for the changes in nanomechanical properties using the nanoindentation technique. Titanium-based nanoparticles were incorporated by two different methods. The nanocoating compositions were studied with the Fourier Transform Infrared spectroscopy (FTIR) and Raman spectroscopy. The surface morphology of the nanocoatings was studied with Atomic Force Microscopy (AFM) and Transmission Electron Microscopy (TEM). The nanomechanical properties of the nanocoatings were studied using the standard nanoindentation test method and the new substrate independent nanoindentation test method. The results obtained from the two test methods confirm the validity of the model used to develop the substrate independent nanoindentation test method. In brief, this study discusses the development of silicone based nanocoating materials and nanomechanical properties of green nanocoatings containing two different types of nanoparticles, evaluated using two different test methods.
