Improved electric properties of degraded liquid crystal using metal-organic frameworks

A series of experiments are conducted to examine the purification effect on degraded liquid crystal (LC) by soaking porous metal-organic frameworks in the LC material. The results indicate that the electric properties of the degraded LC are dramatically improved due to the adsorption and removal of moisture and impurity ions, most likely originating from the atmosphere. This investigation leads to the advancement in the feasible recycling of deteriorated LC materials, including LC leftovers from flat-panel production lines, with a simple and cost-effective treatment method.
