使用硅烷偶联剂KH570对孔隙率不同的泡沫铝合金进行表面改性后，通过注塑成型法制备了聚甲醛/泡沫铝合金互穿复合材料.采用傅立叶变换红外光谱仪(FT-IR)、扫描电子显微镜(SEM)和导热系数测试仪分别研究了改性后的泡沫铝合金的表面的红外结构、复合材料的界面结合问题以及所制备复合材料的导热性能.结果表明，硅烷偶联剂KH570成功接枝到了泡沫铝合金的表面；泡沫铝合金与聚甲醛两相界面结合良好；泡沫铝合金的充填提高了复合材料的导热性能.当泡沫铝合金孔隙率为60．48％~75．41％时，聚甲醛/泡沫铝合金互穿复合材料的导热系数随孔隙率(λ)的增大而降低，其导热系数在10．2945~17．6471 W/(m·K)之间.

Polyoxymethylene(POM)/Aluminum alloy foam Interpenetrating Phase Composites were prepared by injection molding technique after aluminum foam was modified by silane coupling agent KH570.FT-IR spectro-photometer,scanning election microscope(SEM)and thermal conductivity meter were employed to research the infrared structure of the modified aluminum alloy foam,the interfacial bonding and the heat transfer perform-ance of the POM/aluminum alloy foam interpenetrating phase composites The results showed that silane cou-pling agent KH570 was grafted to the aluminum alloy surface,The interface between aluminum alloy and POM were bonding well,the heat transfer performance of composites improved with the filling with aluminum alloy foam.When the porosity of aluminum alloy foam were ranged from 60.48% to 75.41%,the thermal conductivi-ty of the POM/aluminum alloy foam interpenetrating phase composites decreased with the increasing the porosi-ty of Al alloy foam percentage.Then the thermal conductivity of samples was between 10.2945 W/(m·K)to 17.6471 W/(m·K).
