项目摘要

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.

声致变色器件随声激励的变化本课题主要研究声致变色器件随声激励的变化。这项研究是用超声波设备进行的，这种设备可以将频率为23到143 kHz的超声波暴露于聚合物和染料的水溶液成分。将本研究的思路应用于超声辐照后可见光和红外区的吸收光谱监测。实际结果数据表明，超声波影响了包括水溶性染料、季氮苯在内的聚合物水溶液的光谱变化。结果表明，在43 kHz频率下，超声辐照促进了染料在聚丙烯酸水溶液中的聚集。除了这些结果，研究还发现有证据表明，超声波暴露极大地降低了聚合物溶液的粘度。红外分析也支持超声波破坏了聚合物中的氢键，但聚合物的断裂在没有暴露于原始条件下没有分解的情况下被恢复。这些结果表明，超声可以控制水相聚合物中氢键的断裂和形成。将这一现象应用于声刺激变色新器件是可能的。
