Microwaves were used to heat a polymer solution to make a conjugated polymer rotate. With this method, heating can be done quickly, and traditional long-time annealing treatment is not required. Additionally, intermolecular forces are increased, which in turn increases the crystallinity of the conjugated polymer. Thus far, the effect of this process has been tested on Poly(3-hexylthiophene-2,5-diyl) (P3HT) and Diketopyrrolopyrrole-thiophene vinylene thiophene (DPP-TVT). The charge mobility of these two conjugated polymers increased by several times after the microwave treatment. We used atomic force microscopy (AFM) and synchrotron radiation low-angle X-ray diffraction technology (GIXRD) to determine the molecular arrangement and the morphology of the components. Microwave treatment was found to have an effect on the molecular arrangement and surface morphology of the conjugated polymers. In the second part, the researchers proposed a simple process for obtaining an elastic semiconductor by mixing poly (glycerol sebacate) and the conjugated polymer. Through thermal crosslinking, the elastic polymer was crosslinked to protect the conjugated polymer and make it stretchable. The elastic semiconductor produced by this process could be stretched by 100% without any cracks. Moreover, poly (glycerol sebacate) is a biodegradable and biocompatible material. The elastic semiconductor obtained in this study is expected to be applicable in biomedical electronics.
