Sonochemical synthesis and characterization of Ag2S/PVA and CuS/PVA nanocomposite

Ultrasonics Sonochemistry, 2002
Abstract Nanospherical Ag 2 S/PVA and nanoneedles of CuS/PVA composite have been prepared by sonochemical irradiation of a 10% ethylenediamine–water solution of elemental sulfur, silver nitrate, or copper acetate in the presence of polyvinyl alcohol. The particle sizes are 25 and 225 nm for Ag 2 S/PVA and CuS/PVA nanocomposites, respectively.

Effect of γ-Ray Irradiation on Mechanical Properties of PVA and Acetalized PVA Films

Kobunshi Kagaku, 1961
およびアセタール化PVA皮膜の強伸度に及ぼすγ 線の照射効果について研究した。照射は室温で真空中および空気中で行なった。熱処理した皮膜は真空中空気中いずれで照射しても, よく似た挙動を示し140℃ で熱処理した皮膜の強度は4×107r程度の照射により15%程度増加し, 200℃ で熱処理した皮膜では照射によりほとんど変らなかった。伸度は両皮膜共照射量の増加とともに減少した。アセタール化皮膜の強伸度は真空中空気中いずれで照射してもかなり低下し特に空気中照射の場合の低下は著しい。
