Abstract

The use of pulsed acoustic microscopy (50–200 MHz) makes it possible to analyze the three-dimensional microstructure and uniformity of the elastic properties of hydrated composite biomaterials. This paper proposes a method for local assessment of acoustic properties in spongy polymer samples, based on visualizing the microstructure, measuring attenuation, and sound velocity. This approach is relevant to the study of biopolymer composite materials and their structures, as it allows for in situ observation of structural degradation under external influences, as well as investigation of the evolution of native tissue replacement, if necessary.

脉冲声显微镜在壳聚糖基生物复合海绵研究中的应用

利用脉冲声显微镜（50-200 MHz）可以分析水合复合生物材料的三维微观结构和弹性性能的均匀性。本文提出了一种基于微观结构可视化、衰减测量和声速测量的海绵状聚合物样品声特性局部评价方法。这种方法与生物聚合物复合材料及其结构的研究相关，因为它允许在外部影响下原位观察结构降解，以及必要时研究天然组织替代的演变。
