Sonochromic device changing with sound stimuliThis research project is focused on sonochromic device changing with sound stimuli. The subject was studied with ultrasound equipments, which could expose ultrasound having 23 to 143kHz frequencies to aqueous components of polymers and dyes. The idea on this research was applied to be monitored absorption spectra of visible and infrared regions after the ultrasound exposed. Actually resultant data implied that ultrasound influenced the spectral changes of aqueous polymer solution including water-soluble dye, quaternary azopridium benzene. The results suggest that the ultrasound exposure with 43 kHz frequency enhanced the dye aggregation in the aqueous soluble polymer solution for poly acrylic acid. In addition with these results, the research found evidence on that ultrasound exposure extremely reduced the polymer solution viscosity. Infrared analysis also supported that ultrasound broke hydrogen bondings in the polymers.But, the breaking of the polymer was recovered without the exposure to the original condition without decomposition. These results indicated that ultrasound could control the hydrogen bonding breaking and formation in the aqueous polymers. There is possibility to apply this phenomena for new device to sound stimuli-chromism.

随着声音刺激而变化的声致变色装置本研究项目的重点是随着声音刺激而变化的声致变色装置。该课题通过超声波设备进行研究，该设备可以将频率为 23 至 143kHz 的超声波暴露于聚合物和染料的水性成分中。这项研究的想法被应用于监测超声波照射后可见光和红外区域的吸收光谱。实际上所得数据表明超声波影响了包括水溶性染料、季氮吡啶苯的聚合物水溶液的光谱变化。结果表明，43 kHz频率的超声波照射增强了聚丙烯酸水溶性聚合物溶液中的染料聚集。除了这些结果之外，研究还发现了超声波暴露极大降低了聚合物溶液粘度的证据。红外分析也支持超声波破坏了聚合物中的氢键。但是，聚合物的破坏在没有暴露于原始条件而不分解的情况下恢复了。这些结果表明超声波可以控制水性聚合物中氢键的断裂和形成。有可能将这种现象应用到声音刺激色的新设备中。
