PVDFtä
PVDFtä is a class of polymers derived from polyvinylidene fluoride (PVDF). It designates PVDF-based materials that have been functionalized with side groups, referred to here as tä moieties, to tailor surface properties while retaining the core fluoropolymer characteristics. The term appears in contemporary polymer research as a designation for this family.
Chemically, PVDFtä materials keep the semi-crystalline PVDF backbone; functionalization is achieved by grafting or copolymerization, introducing
Key properties include high chemical resistance and thermal stability similar to PVDF, with tunable surface energy
Synthesis and processing: PVDFtä can be prepared by post-polymerization grafting onto PVDF backbones or by copolymerization
Applications: PVDFtä materials are investigated for membranes in water and gas separation, corrosion-resistant coatings, protective films,
Limitations and outlook: higher processing viscosity, potential reductions in crystallinity, and cost considerations require optimized formulations.
