Abstract
Nanomaterijali i nanotehnologija postali su jedno od najistraživanijih područja u posljednjem desetljeću. Osim po njihovim izvrsnim svojstvima prepoznatljivi su i po mogućnosti primjene u gotovo svim granama industrije. Poseban interes izazivaju ugljikove nanocijevi. Izvanredna mehanička i električna svojstva omogućavaju njihovu primjenu u izradi minijaturiziranih vodljivih komponenti. Zbog svojih svojstava, stabilizacija ugljikovih nanocijevi predstavlja ključan problem za dobivanje funkcionalnih suspenzija za izradu vodljivih filmova. U ovom radu cilj je bio pripremiti stabilne suspenzije višestjenčanih nanocijevi u organskim otapalima (etanol i smjesa otapala) uz polimerni stabilizator polivinil butiral (PVB). Stabilnost se pratila tijekom vremenskog perioda od tjedan dana snimajući UV-Vis apsorpcijske spektre. Dobivene su stabilnije suspenzije u smjesi otapala, a u oba otapala dolazi do pojave aglomeriranja. Nakapavanjem stabilnije suspenzije na polimerne podloge proizveli su se vodljivi filmovi, kojima je određen površinski električni otpor. Dobiveni uzorci su nakon toplinske obrade pokazali zadovoljavajuću električnu vodljivost (osobito uzorci sušeni na višim temperaturama) te potencijalnu primjenu u izradi vodljivih elektroničkih komponenti.
Abstract (english)
Nanomaterials and nanotechnology have become one of the most researched areas in the last decade. In addition to their excellent properties, they are also recognizable by the possibility of application in almost all branches of industry. Carbon nanotubes are of particular interest. Outstanding mechanical and electrical properties enable their use in the production of miniaturized conductive components. Due to its properties, the stabilization of carbon nanotubes represents a key problem for obtaining functional suspensions for making conductive films. In this work, the goal was to prepare stable suspensions of multi-walled nanotubes in organic solvents (ethanol and solvent mixture) with the polymer stabilizer polyvinyl butyral (PVB). Stability was monitored over a period of one week by recording UV-Vis absorption spectra. More stable suspensions were obtained in the mixture of solvents, and agglomeration occurs in both solvents. By dripping a more stable suspension onto polymer substrates, conductive films were produced, the surface electrical resistance of which was determined. After heat treatment, the obtained samples showed satisfactory electrical conductivity (especially samples dried at higher temperatures) and potential application in the production of conductive electronic components.
