Thermoelectric Potential of Polymer-Scaffolded Ionic Liquid Membranes

摘要: Organic thin films have been viewed as potential thermoelectric (TE) materials, given their ease of fabrication, flexibility, cost effectiveness, and low thermal conductivity. However, intrinsically electrical conductivity is a main drawback which results in relatively lower TE figure merit for polymer-based materials than inorganic materials. In this paper, technique to enhance the ion transport properties polymers through introduction ionic liquids presented. The polymer form nanofiber scaffold produced using electrospinning technique. These fibers were then soaked different based on substituted imidazolium such 1-ethyl-3-methylimidazolium chloride or 1-butyl-3-methylimidazolium bromide. This method was applied electrospun polyacrylonitrile mixture polyvinyl alcohol chitosan polymers. membranes observed increase with increasing concentration liquid, maximum 1.20 × 10−1 S/cm measured at room temperature. Interestingly, value surpassed pure liquids. indicate that it possible significantly improve membrane simple cost-effective method. may turn boost figures are well known be considerably those Results terms Seebeck coefficient also presented paper provide an overall representation polymer-scaffolded liquid membranes.
