There is a high demand for a volatile-organic-compound (VOC)-free approach to converting high performance polymers (HPPs), such as polyetherketoneketone (PEKK), to porous structures. This is particularly true for achieving flexible foams from these very rigid HPPs. This current work introduces a facile and environmentally benign approach to fabricating flexible PEKK foams via a hydration-induced foaming and desulfonation treatment. This foaming technique possesses three major advantages: energy… CONTINUE READING
