Surface modifications with nanoparticles are major concerns in the realization of the full potential of nanoscale devices. Currently, no single surface treatment technology can solve all problems of reliability. Further, precise control of nanoparticle coatings is still lacking. Therefore, the goal of this research was to obtain a fundamental understanding of the way in which the surface chemistry and deposition conditions of the nanoparticles affect the films achieved. With such an improved understanding, it will be possible to achieve well-controlled nanoparticle coatings with the properties desired. The work presented here demonstrated the possibility that the surface morphology of GXL-deposited nanoparticle films can be controlled during synthesis by changing the surface chemistry of the nanoparticles or substrates. By using VPD, durable, superhydrophobic nanoparticle coatings can be applied to commercial devices and their chemical and physical properties specified. This work has the potential to make nanoparticle coatings more attractive for realistic applications and market consumers.
