Macroporous, low-density polyetheretherketone, polyetherketoneketone, and polyetherimide foams are produced using a high-temperature, thermally induced phase separation method. A high-boiling-point solvent, which is suitable to dissolve at least 20 wt% of these high-performance polymers at temperatures above 250 °C, is identified. The foam morphology is controlled by the cooling procedure. The resulting polymer foams have porosities close to 80% with surface areas up to 140 m g and elastic moduli up to 97 MPa.
采用高温热致相分离法制备了具有大孔、低密度结构的聚醚醚酮、聚醚酮酮和聚醚酰亚胺泡沫材料。筛选出了一种高温高沸点溶剂，该溶剂在 250°C 以上的温度下能够溶解至少 20wt%的这些高性能聚合物。通过冷却过程控制泡沫形态。所得到的聚合物泡沫具有接近 80%的孔隙率，比表面积高达 140m²/g，弹性模量高达 97MPa。
