摘要: Abstract Interest lies in the creation of novel nanocomposite materials obtained through mixing, impregnation or incorporation techniques. One such technique is ion implantation which possesses potential for retaining properties from base material and implanted as well any effects observed combining two. To this end low-energy (15 keV) lead ions various fluences was performed conducting polypyrrole films. The presence lead-rich particles evidenced transmission electron microscopy. An interesting trend between fluence conductivity. Of tested, optimum films enhanced conductivity are 5 × 1014 at. cm−2 2 × 1015 at. cm−2. stability appear to result a combination effects: polymer degradation arising beam damage, an increase charge-carriers (dications) present after precipitation Pb-rich nanoparticles. Monitoring over time showed increased retention levels implantation. Improvements open avenues application bring one step closer practical use. A mechanism suggested advantageous retained
