Of the experiments performed in this work, I will discuss in detail the surprisingly complicated steps that result from placing a drop of water on a hydrophilic substrate having a carbon nanotube deposit. The study is a continuation of previous experiments, in a recent doctoral dissertation.\n\nWhen a drop of water first expands and then dries, it is imaged with a long-distance microscope. It was found that carbon nanotubes end up on top of the water droplet. Here, the nanotubes form networks, probably due to capillary forces. After the droplet dries, the networked deposit remains on the surface of the silicon. This so-called redeposition can be examined after the experiment with optical and electron microscopy. In addition, the redeposition could be classified into different categories. These categories include chains, a deposit ring, and other redoposition types. No clear dependence on parameters was found for all these types. In addition, it was found that the outer diameter of the empty ring formed for the deposit corresponds to the droplet dimension calculated with a spherical model.\n\nIn the research, the variable parameters were the relative humidity, the temperature of the sample base, the size of the droplet and the amount of deposition on the silicon surface. These parameters were found to have some effect on the redeposition, but the exact effect remains a somewhat open question.\n\nIn this thesis I also review the equipment needed to conduct the research.
