The silver ion release from PA6 filled with 2wt% nanosilver obeys a zero-order rate law for at least 100days. During this time about 17μg silver per day, per litre immersion liquid and per cm2 sample surface are released. The PA6/Ag-nanocomposite was shown to be active against Escherichia coli whereas the pure PA6 did not show any antimicrobial efficacy. Immersion of a nanocomposite containing 2wt% silver in water for 100days does not reduce its antimicrobial efficacy against Escherichia coli. Thus PA6 filled with 2wt% nanosilver is an effective antimicrobial material for long-term applications.
