Controlling pesticide release via structuring agropolymer and nanoclays based materials

► New controlled-release pesticide carriers are designed by combining wheat gluten and nanoclays. ► The material formulation influences the transfer properties of the delivery system. ► The nanocomposite structure depends on the affinity between polymer and fillers. ► Tortuosity induced by nanoclays is not significant to slowdown pesticide release. ► The release behavior is driven by specific interactions between pesticide and clays.
