Poly(methyl methacrylate) / Multiwalled Carbon Nanotubes Composites Prepared by Solvent Cast Technique and Percolation Threshold

Original language description

Polymer composites based on poly(methyl metacrylate)/multi-wall carbon nanotubes, (PMMA/MWNT), were prepared by solvent cast technique from dispersions of MWNT in PMMA solutions. The three different solvents like toluene, chloroform and acetone to solvePMMA covering broad range of Hansen solubility parameters were selected. Composite mixing was done by sonication of solutions with MWNT in broad concentration range up to 20 wt. % of MWNT. Electrical conductivity of composites as a function of MWNT concentration was measured. The different percolation thresholds were found for used systems like PMMA/solvent/MWNT which were found to be related onto values of Hansen solubility parameters. Increasing of dispersion component together with lower values of polar and hydrogen bonding components leads to lower value of percolation threshold.

Poly(methyl methacrylate) / Multiwalled Carbon Nanotubes komposity připravené z roztoku a jejich perkolační práh

Czech description

Polymerní kompozity na bázi PMMA/více vrstvá uhlíková nano-trubice byly připraveny pomocí odlévání polymerních disperzí. Toluen, chloroform a aceton mající různé hodnoty Hansenových parametrů rozpustnosti byly použity. Míchání za použití ultrazvuku byloupřednostněno. Elektrická vodivost kompozitů byla měřena v závislosti na koncentraci plniva. Poloha perkolačního prahu závisí na parametrech rozpustnosti.
