dc.description.abstract Polymerní kompozity na bázi PMMA/MWNT byly připraveny odléváním disperzí CNT z různých rozpouštědel jako jsou toluen, chloroform a aceton. Míchání probíhalo pomocí ultrazvuku a koncentrace CNT do 20 hm. %. Různý perkolační práh byl nalezen pro různé rozpouštědla korelujíce s Hansenovými parametry rozpustnosti. cs
dc.description.abstract Polymer composites based on poly(methyl metacrylate)/multi-wall carbon nanotubes, (PMMA/MWNT), were prepared by the solvent cast technique from dispersions of MWNT in PMMA solutions. Three different solvents like toluene, chloroform and acetone were selected to solve PMMA, covering a broad range of Hansen solubility parameters. Composite mixing was done by sonication of solutions with MWNT in a 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 the dispersion component together with lower values of polar and hydrogen bonding components leads to a lower value of the percolation threshold. en
