When the hybrid was irradiated with a low-pressure mercury lamp, the transmittance at 620 nm in the UV-visible spectra decreased and the color changed from pale yellow to blue. This means that amorphous WO<SUB>3</SUB> have changed to the tungsten bronze structure. After irradiation the films bleached with elapsed time in the dark. Temperature dependence of the dynamic viscoelasticity of the PTMO/WO<SUB>3</SUB> hybrid was measured. A sharp peak at about -55°C in the tan 5 curves is due to microBrownian motion of PTMO segments. The peak position did not change below 15wt% of WO<SUB>3</SUB> content, but above 30wt% it shifted to a higher temperature and the peak broadened. The storage modulus of the hybrids at the rubbery region increased with increasing amount of WO<SUB>3</SUB>. A broad peak in small-angle X-ray scattering profiles was caused by the interference between terminated silica domains. The peak position shifted to a lower angle, and the peak disappeared with increasing amount of WO<SUB>3</SUB>. These results suggest that the WO<SUB>3</SUB> domains may be formed in the vicinity of silica domains below 15% of WO<SUB>3</SUB> content, but dispersed in the PTMO matrix above 30% WO<SUB>3</SUB>and strongly restricts the molecular motion of the PTMO segments."},{"@value":"ポリテトラメチレンオキシド (PTMO) と三酸化タングステン (WO<SUB>3</SUB>) をゾルーゲル法により複合し, 透明なハイブリッドフィルムを得た. ハイブリッドに紫外線を照射すると時間とともに淡黄色から青色に変化した. これは, 無定形WO<SUB>3</SUB>がタングステンブロンズ構造に変化することを示す. 青色に変色した試料は暗所放置時間とともにブリーチングした. 短時間の紫外線照射・暗所放置の繰返しでも良好なフォトクロミック特性を示した. 動的粘弾性の温度依存性の測定からPTMOセグメントのミクロブラウン運動による-55℃付近のtanδピークは, WO<SUB>3</SUB>が15wt%までは順次低くなるが, それ以上では低くかつブロードになり高温側に移動した. 室温付近以上でゴム弾性を示し, その弾性率の値はWO<SUB>3</SUB>が少量のときは10MPa程度であるが, 30%では1桁高くなり, 55%ではさらに1桁高くなった.
