Encapsulation of Imazamox within MOF Mixed Matrix Membranes and Its Voltage-Dependent Release

In recent years, the application of metal–organic frameworks (MOFs) in various fields has received extensive attention. MOFs are considered promising pesticide delivery nanocarriers due to their well-defined structure, high surface area, high porosity, and tunable pore size. We have developed a hybrid matrix membrane with controlled release by voltage, UiO-66-NH2, for the controlled release of pesticides. In this paper, Imazamox was taken as an example to conduct an experimental product analysis. It was found that the immobilization of Imazamox was 22.38 ± 0.12 mg/g. The subsequent stepwise controlled release of Imazamox under the specificity of electric field force and stimulus-response reached 96.10%, which proposed another method to develop pesticide controlled release technology, which is expected to develop more functionalized controlled release devices suitable for different pesticide molecules. It provides an idea for the practical application of agricultural production and the safe and reasonable application of pesticides.
