摘要

聚偏二氟乙烯（PVDF）胶乳纳米粒子是 PVDF 制造过程中的前驱体，因此是一种用途广泛的表面改性平台。然而，聚偏二氟乙烯（PVDF）化学稳定性强、相容性差，给有效的表面改性带来了巨大挑战。为此，我们开发了一种通过链缠结促进表面改性的方法。通过采用单体溶胀乳液聚合法，将聚甲基丙烯酸酯（PA）单体加入到 PVDF 纳米颗粒中，然后进行聚合。流变学特性和透射电子显微镜图谱证实了 PVDF 和 PA 之间的链缠结，表明整合成功。该方法高效、直接、适应性强，非常适合大规模工业化生产。

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.
