The object of this study is to develop an intelligent polymeric material in which cracks can be healed by microwave irradiation. The reaction by microwave irradiation has advantages such as better process control, faster curing times, and higher yields compared with the reaction by conventional heating. Perfluorocyclobutane (PFCB)-containing polymers have been studied as a unique class of fluoropolymers having excellent properties such as low dielectric constant, good thermal stability, high Tg, and optical transparency. In this work, the potential of a PFCB polymer as a mendable material was investigated by means of microwave irradiation. Crack were generated in PFCB polymer specimens, and a part of the cracked samples were healed by microwave re-irradiation. The crack-healing ability of the polymers was investigated by FT-IR. The crack healing in the polymers was successfully demonstrated by the measurement of flexural strength of the polymer specimens before and after healing. |
