It also allowed estimation of the apparent solubility in the polymer. However, SEM investigations revealed that a portion of the insecticide is trapped, in a crystalline state, inside the polymer matrix.en© 2020 Author(s)ChlorfenapyrMigrationPolymer matrixPolymer filmFourier-transform infrared spectroscopy (FTIR)Scanning electron microscopy (SEM)Attenuated total reflection (ATR)Article
