Polyaniline/montmorillonite nanocomposite thin layers deposited on different substrates

Popis výsledku v původním jazyce

Preparation method of polyaniline/montmorillonite (PANI/MMT) nanocomposite thin layers deposited on various substrates was optimized to obtain high electrical conductivity. Simple method, i.e. polymerization of anilinium sulfate in the presence of MMT, has been used for the preparation and following four conditions were varied: preparation temperature (T = 10 or 20 °C), deposition time (t = 4 or 6 h), size fraction of MMT (p &lt; 1 or 5 μm), and type of substrate (microscope glass slides, silica glass slides, polyester foils). Therefore, 24 samples were prepared, characterized and their electrical conductivities were compared. Raman spectroscopy and SEM were used for the characterization of the structure of samples. Thickness of layers was measured using AFM. Based on the comparison of samples and with respect to the aim of obtaining high electrical conductivity, it was found that the most suitable substrate is polyester foil and the most suitable preparation conditions are T = 20 °C, t = 6 h, p &lt; 5 μm. To obtain highly conductive layers on glass substrates (although less conductive than layers on foil), deposition time have to be shortened to 4 h.
