The object of this study is to develop an intelligent polymeric material that heals cracks through microwave irradiation. Microwave irradiation has many advantages in the healing reaction such as better process control, faster curing times, and higher yields compared with 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. Cracks were generated in the polymer specimens, and a part of the cracked samples were irradiated with microwave to induce healing reaction. 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. |
