Surface Modification of Polyvinylidene Fluoride Latex Nanoparticles through Chain Entanglement by Poly(meth)acrylate Monomer Swelling Seeded Emulsion Polymerization

Polyvinylidene fluoride (PVDF) latex nanoparticles serve as a versatile platform for surface modification due to their role as precursors in PVDF manufacturing. However, the strong chemical stability and poor compatibility of PVDF present significant challenges for effective surface modification. To address this, we developed a method that facilitates surface modification through chain entanglement. By employing monomer swelling emulsion polymerization, poly(meth)acrylate (PA) monomers are incorporated into PVDF nanoparticles and subsequently polymerized. Rheological properties and transmission electron microscopy mapping confirmed the chain entanglement between PVDF and PA, indicating a successful integration. This method is efficient, straightforward, and highly adaptable, making it well-suited for large-scale industrial production.
