Resumen:
Thin films of polymerized acetylene have been deposited by Plasma Enhanced Chemical Vapor Deposition 20films of polymerized acetylene have been deposited by Plasma Enhanced Chemical Vapor Deposition 20 with a capacitively coupled RF discharge of acetylene. From the results of elemental analysis, FTIR, 1H-NMR 211H-NMR 21 and electrical conductivity, a highly branched chemical structure for the polymeric film is proposed. The 22film is proposed. The 22 morphology of the film surface, as well as its thickness was determined by scanning electron microscopy. The 23film surface, as well as its thickness was determined by scanning electron microscopy. The 23 optical constants of the film, refractive index and optical band gap energywere obtained by the UV?vis transmit- 24film, refractive index and optical band gap energywere obtained by the UV?vis transmit- 24 tance spectrum using differentmodels from the literature. The films presented amoderate degree of hydropho- 25films presented amoderate degree of hydropho- 25 bicity and showed a high capacity to absorb and retain benzene after drying at room temperature during 24 h. 2626 This result shows the potential of the obtained polymer to be used in filler of filters employed for the treatment 27filler of filters employed for the treatment 27 of industrial effluents.fluents.
