高回弹有机硅改性聚酰亚胺泡沫材料的设计及性能
Design and Properties of High Resilience Silicone Modified Polyimide Foam Materials
摘要
Abstract
IIn this paper,a series of high resilience silicone-modified polyimide foams(IBPIF-Si)were prepared.The pore structure,mechanical properties,foaming principles and the highest operating temperature of IBPIF-Si were investigated.Compared to pure IBPIF,IBPIF-Si showed the low density[(22.0±6.7)mg/cm3)],high porosity(97.93%),excellent hydrophobic[the water contact angle was(128±2.72)°]and outstanding flexibility(with a linear elastic region was 0~14.77%).This unique modification method broadened the potential application of polyimide foam in the aerospace sector,including heat insulation,noise reduction,insulation and other aspects.关键词
