Abstract In this study, silicone rubber foam (SF) was prepared through cross-linking and foaming. The effects of ethanol content on the SF were investigated in terms of the physical properties, static cushioning properties, dynamic thermomechanical properties, and dynamic fatigue properties. The cell structure was characterized using scanning electron microscopy and its relationship with the SF properties was analyzed. With increasing ethanol content, the cell diameter increases gradually and its uniformity deteriorates. Moreover, the density, tensile strength, and elongation at breaking of the SF samples gradually decrease. In addition, with the increase of strain and stress, the cushioning coefficient of SF decreases initially and then increases, and the fatigue times worsens with increasing ethanol content. However, fatigue process has little effect on the cushioning performance of SF, which means the SF can be used as reusable packaging materials and thereby reduce environmental pollution.

乙醇含量对硅橡胶泡沫性能的影响

摘要 本研究通过交联和发泡制备硅橡胶泡沫（SF）。从物理性能、静态缓冲性能、动态热机械性能和动态疲劳性能方面研究了乙醇含量对 SF 的影响。使用扫描电子显微镜表征细胞结构并分析其与SF性质的关系。随着乙醇含量的增加，细胞直径逐渐增大，均匀度变差。此外，SF 样品的密度、拉伸强度和断裂伸长率逐渐降低。此外，随着应变和应力的增加，SF的缓冲系数先降低后增加，疲劳时间随着乙醇含量的增加而恶化。然而，
