| Research Abstract |
The effect of nano-particles on the conductivities of PAS/PVA/nano-particles was studied. The following conclusion was gotten in this study.
(1) Addition of inorganic nano-particles (TiO_2, Al_2O_3, and ITO) into PAS/PVA composites influenced their conductivities. TiO_2 particle was the most effective for the increase of the conductivity of PAS/PVA composites among the examined nano-particles.
(2) The increase of conductivity of the PAS/PVA/nano-particles composites is possibly related to PAS adsorbability of the filled nano-particles. The model experiment with the use of electrophoresis instrument suggested that moderate (weak) PAS adsorbability of TiO_2 is effective for the formation of PAS molecule extended layers and PAS networks, resulting in the increase of the conductivity of the PAS/TiO_2 composites. ITO has a strong adsorbability to PAS molecules, but ITO exhibits a gradual increase of conductivity. The slight increase of the conductivity of PAS/PVA/ITO is attributable to the excellent conductivity of ITO particles.
