AI Technical Summary
In the existing technology, the preparation of PEDOT dispersions suffers from slow low-temperature polymerization rates, low production efficiency, high energy consumption, uneven particle size, poor stability, and traditional dispersion methods are prone to agglomeration and impurity introduction, resulting in low conductivity, which makes it difficult to meet the requirements of high-end flexible electronic and optoelectronic devices.
Supercritical dispersion technology, combined with compound dopants and UV crosslinking agents, is used to prepare conductive polymer PEDOT dispersions by polymerization under supercritical conditions. The synergistic effect of perfluorosulfonic acid resin and sulfonated polyether ether ketone forms a stable binding structure. Combined with UV curing process, the crosslinking network can be precisely controlled.
It significantly improves the conductivity and environmental adaptability of PEDOT dispersions, ensures dispersion stability and film uniformity, extends service life, and meets the long-term stability requirements of flexible electronics and transparent electrodes.
