中文摘要：

以戊二醛（Glu）胶联丙烯酰胺（AM）形成的软物质凝胶材料的成胶过程为模型,用超声衰减法检测不同浓度交联剂、温度及不同质量丙烯酰胺形成凝胶的成胶过程的微结构变化.同时用流变仪检测凝胶形成过程中粘弹性等参数的变化.实验表明：丙烯酰胺浓度、交联剂的用量和温度不同,丙烯酰胺形成凝胶的超声衰减系数及所需的时间也不相同,丙烯酰胺浓度越大,超声衰减系数越大,凝胶形成越快;温度越高,交联剂的量越多,丙烯酰胺凝胶形成所需的时间越短.

英文摘要：

The applicability of ultrasonic attenuation measurements was discussed when the microstructural change status of acrylamide gel soft materials formation was studied with different concen- tration glutaraldehyde cross-linked, acrylamide and temperature as model systems. Rheological method is the measurements of changes of viscoelastic parameters in gel formation process by rheometer de- tection as contrast. It was shown that： the bigger the acrylamide concentration is, the greater the ultrasonic attenuation coefficient and the sooner of gel formation, the acrylamide gel is formed faster in the higher of temperature, the acrylamide gel is formed faster in the higher of crosslinker. It is predicted that the ultrasonic attenuation measurements can be developed into a simple, effective, nonstructive and reliable technique to soft materials formation.
