1. Synthesis and Characterization of Nanoparticle Thin Film (NTF)
Nanoparticle thin films (NTFs), i.e. thin films composed of nanoparticles, exhibit synergistic properties, making them useful for numerous advanced applications. However, many NTFs have a poor resistance to mechanical loading and abrasion, presenting a major bottleneck to their widespread use and commercialization. We are working on providing techniques to greatly increase the mechanical durability of NTFs. We have demonstrated that atomic layer deposition (ALD) at a relatively low temperature can drastically improve the mechanical durability of nanoparticle films on organic and inorganic substrates. This research is a collaborative project with Dr. Daeyeon Lee at University of Pennsylvania.
