Polyimide foams,due to the outstanding combined properties including low dielectric and thermal insulating,acoustic absorbing,high strength-to-weight ratio,cost effectiveness,etc.,have been extensively used in many high-tech fields such as the aerospace,aviation,ship,energy and environmental protection,etc.,in recent years. There are two types of polyimide foams,the soft one having opened-cell in structures and the rigid one having closed-cell in structures. Polyimide foams are usually produced by thermal f...
