Popis: Cilj ovog rada je opisati kemijska i fizikalna svojstva nanocjevčica (NT), njihovu primjenu te detaljno objasniti sintezu i strukturu ugljikovih nanocjevčice (CNTs) i nanocjevčica titanijevog dioksida (TiO₂NTs). Nanostrukturiranim materijalima smatraju se materijali kojima je najmanje jedna dimenzija na nano razini, između 1 i 100 nm, a kod nanocjevčica je to promjer, dok duljina može biti i do 500 mm. Upravo zbog visokog omjera duljine i promjera odlikuju izvrsnim električnim, mehaničkim i optičkim svojstvima. U radu su detaljno razrađene i metode karakterizacije nanocjevčica: skenirajuća elektronska mikroskopija (SEM), transmisijska elektronska mikroskopija (TEM), skenirajuća mikroskopija s tuneliranjem (STM), energijski razlučujuća rendgenska spektroskopija (EDS), rendgenska difrakcija (XRD) i Ramanova spektroskopija. The aim of this paper is to show the chemical and physical properties of nanotubes (NT), their application and explain in detail the synthesis and structure of carbon nanotubes (CNTs) and titanium dioxide nanotubes (TiO₂NTs). Nanostructured materials are considered materials with least one dimension at the nano level, between 1 and 100 nm, and in the case of nanotubes it is the diameter, while the length can be up to 500 mm. Precisely because of the high ratio of length and diameter, they are characterized by excellent electrical, mechanical and optical properties. The paper also elaborates in detail the methods of characterization of nanotubes: scanning electron microscopy (SEM), transmission electron microscopy (TEM), scanning tunneling microscopy (STM), energy-dispersive X-ray spectroscopy (EDS), X - ray diffraction (XRD) and Raman spectroscopy.
