| 中文摘要: |
| 有机硅泡沫材料因独特的无机-有机杂化结构使其具有良好的阻燃性能、耐高低温性能、化学稳定性，又因含有大量泡孔结构而具有缓冲减震、质量小、隔音隔热、吸声等优良特性，被广泛应用于生物医学、航天航空、电子设备等领域。有机硅泡沫材料的制备方法有化学发泡法（内发泡法和外加发泡剂法）、物理发泡法（3D打印法、溶析成孔法和惰性气体法）、模具法、辐射交联法、混合发泡法等多种方法。随着对有机硅泡沫材料研究地不断深入，绿色化、功能化和低成本将是其未来研究的重要方向。 |
| 英文摘要: |
| Silicone foams have flame retardancy，high and low temperature resistance and chemical stability due to their unique inorganic - organic hybrid structure. Because of large amount of cellular structure，they have excellent properties such as damping，light weight，sound insulation，heat insulation and sound absorption. They are widely used in biomedicine，aerospace，electronic equipment and other fields. The preparation methods of silicone foams include chemical foaming method（internal foaming and external foaming with addition of foaming agent），physical foaming method（3D printing，pores forming by solvent dissolution，and inert gas method），mold method，radiation crosslinking method，and mixed foaming method. With the deepening of research on silicone foams，development of green materials and process，functionalization and cost reduction are the important directions for future research. |
