Abstract
This work presents a study about the synthesis of polyfuran films by plasma and their structural, morphological, electrical and hydrophilic characteristics. The syntheses were carried out at low pressure with resistive electrical glow discharges. The films have thickness in the 7–61 μm interval with a linear tendency as a function of the power of synthesis. The functional groups of the monomer, –C=C– and C–O, and other as C=O produced during the polymerization, were found in the polymers probably as dehydrogenation of =C–H groups in the monomer. The films have contact angles between 52° and 92° for distilled water, but with the addition of salts in KR solutions, the angles slightly increased reducing the hydrophilicity of the system. The conductivity of polyfuran films was calculated in the range of 10−9–10−11 S/m with two trends, one with high electronic activation energy at low temperature, and another with low activation energy at high temperature. The electronic activation energy in the first trend varied between 1.01 and 1.9 eV and in the second trend between 0.26 and 0.08 eV.
