In this paper, novel rigid polyurethane foams modified with Baltic Sea biomass were compared with traditional petro-based polyurethane foam as reference sample. A special attention was focused on complex studies of microstructure, which was visualized and measured in 3D with high-resolution microcomputed tomography (microCT) and, as commonly applied for this purpose, scanning electron microscopy (SEM). The impact of pore volume, area, shape and orientation on appearance density and thermal insulation properties of polyurethane foams was determined. The results presented in the paper confirm that microcomputed tomography is a useful tool for relatively quick estimation of polyurethane foams' microstructure, what is crucial especially in the case of thermal insulation materials.
在本文中，将用波罗的海生物质改性的新型硬质聚氨酯泡沫与作为参考样品的传统石油基聚氨酯泡沫进行了比较。特别关注了微观结构的综合研究，通过高分辨率微型计算机断层扫描（microCT）以三维方式对其进行可视化和测量，并像通常为此目的所做的那样，使用扫描电子显微镜（SEM）。确定了孔体积、面积、形状和取向对聚氨酯泡沫外观密度和隔热性能的影响。本文给出的结果证实，微型计算机断层扫描是相对快速估算聚氨酯泡沫微观结构的有用工具，这对于隔热材料而言尤为关键。
