PACS numbers: 68.37.Ps, 68.55.jd, 73.61.Ph, 78.40.Me, 82.35.Cd, 82.45.Wx

The polymer-nanoparticles’ thin films are fabricated by anchoring polymer from reaction solution (monomer, alcohol and hydrochloric acid). The thickness of the film increases with time and concentration of monomer and acid, and it decreases at large concentrations of acid. The films have a rough surface and peaks several times greater than the thickness. Thin films are formed on a substrate of gold, ordinary glass and quartz. Film thickness is between 106 nm and 1296 nm. Based on electrochemical impedance spectroscopy, the ohmic resistances of films are of 1090, 235, 176 and 157 (± 12%) Ohm at thicknesses of 780, 487, 102 and 65 nm, respectively, and the double-layer capacitance is of about 149±0.02 μF/cm².

Key words: polymer thin films, anchoring, 2-formyl pyrrole, polyformyl pyrrole
