本文报道用 N-取代聚丙烯酰胺及其共聚物制备新型超声传导凝胶。文章讨论了结构与声学性能之间的关系。研究了 N-取代聚丙烯酰胺的分子量和功能基团、含水量、浓度等因素对声学性能的影响。实验表明,控制 pH 值、温度、浓度、分子量和交联剂用最可以制备 TM-100医用超声传导凝胶。它的声学性能达到日本 ECHO/GEL N-100和美国 Aquasonic-100水平。毒理实验和临床鉴定表明,TM-100凝胶是对皮肤没有刺激,无毒,安全的医用材料。 This paper reports the preparation of novel ultrasound-conducting gels using N-substituted polyacrylamides and their copolymers. The article discusses the relationship between structure and acoustic performance. The influence of molecular weight, functional group, water content and concentration of N-substituted polyacrylamide on the acoustic properties was studied. Experiments show that, the most controllable pH, temperature, concentration, molecular weight and crosslinking agent can be used to prepare TM-100 medical ultrasound conduction gel. Its acoustic performance to Japan ECHO / GEL N-100 and the United States Aquasonic-100 level. Toxicology experiments and clinical identification showed that TM-100 gel is a non-irritating, non-toxic and safe medical material for the skin.
