Polymer nanocomposites containing noble metal nanoparticles are promising materials for plasmonic applications. In this paper, we report on a high-resolution negative-tone nanocomposite resist based on poly(vinyl alcohol) where silver nanoparticles and nanopatterns are simultaneously generated by electron-beam lithography. Our results indicate nanostructures with a relatively high concentration of nanoparticles and, consequently, an electromagnetic coupling among the nanoparticles. Therefore, the patternable nanocomposite described in this work may be a suitable material for future plasmonic circuitry.

Surface tensions and refractive indexes for binary mixtures of {hexane + ethanol, + 1-propanol, + 1-butanol, + 1-pentanol, + 1-hexanol, + 1-heptanol, and + 1-octanol} have been measured at 298.15 K. Surface tension deviations and changes of refractive index have been also calculated. Excess molar volumes of {hexane + ethanol, + 1-pentanol, and + 1-hexanol} mixtures have been determined at 298.15 K from density data and compared with literature.
