Parent polyaniline was rendered soluble by doping it with functionalized protonic acids (e.g. camphorsulfonic and toluenesulfonic acids) whose counter-ion induces solubility in low boiling point solvents such as chloroform. Condensed monolayers with high collapse pressures (above 30 mN/m) were obtained when an acidic subphase was used. The monolayers could be readily transferred onto hydrophilic substrates in lhe form of Z-type Langmuir-Blodgett films, and most importantly with transfer ratios close to 1. Interestingly, the fllms are readily obtained in the doped form and are electroactive.  aLangmuir  aLB  aPolianilina1 aMATTOSO, L. H. C.1 aMELLO, S. V.1 aTELLES, G. D.1 aOLIVEIRA JÚNIOR, O.
