Multiwire polystyrene (PS) produced by the electrospinning technique was physically characterized in terms of morphology and by optical properties of transmittance and absorbance in the IR and UV-Visible regions. A comparison was presented with the properties of bulk PS and multiwire PS containing graphene oxide (GO) nanoparticles (NPs). The polymer is hydrophobic, and this surface property is enhanced when it has a multiwire morphology, and even more when GO NPs are embedded in it. The wetting angles reach up to about 144°. PS is an optimum dielectric polymer, and its permittivity was measured as a function of frequency. Some possible applications of the produced multiwire PS are presented and discussed.
