Common Application Scenarios
- Chemical processing
PVDF film is used as a contact surface for production, storage and transportation of corrosive fluids.
- Gas and liquid sampling bags
PVDF films are chemically inert and have a very low extractable content. They are very flexible and easy to heat seal.
- Outdoor protection
Excellent weather resistance, UV resistance and abrasion resistance make PVDF film very suitable for laminated billboards, traffic signs and awnings.
- Anti-graffiti applications
Non-stick properties and excellent solvent resistance make PVDF film very valuable in covering high flow areas that need to be cleaned frequently with corrosive solvents and cleaning solutions.
- Photovoltaic panels
Due to its excellent dielectric properties, fire resistance and high solar transmittance, PVDF film is very suitable for the back and front glass of photovoltaic panels.
- PVDF film is a piezoelectric polymer, which is very sensitive to changes in strain applied to it. PVDF film can be used as a belt-type sensor head of a wearable cardiopulmonary signal sensor device to obtain clear cardiopulmonary signals for monitoring family sleep status.

- Using gamma radiation technology to graft styrene (St) and dimethylaminoethyl methacrylate (DMAEMA) on the PVDF film, a new type of amphoteric ion exchange membrane can be prepared through the subsequent sulfonation and protonation process. This amphoteric ion exchange membrane can be used in vanadium redox flow battery (VRFB) systems.

- PVDF film has a special inert polymer with excellent mechanical strength and durability, and has been widely studied in the application of implant components. However, the lack of biocompatibility due to the inherent hydrophobicity of the PVDF surface may limit its use in biomedical applications. Materials used in biomedicine or tissue engineering should provide physicochemical properties and cell motifs that match the surrounding environment to support the required cellular responses, such as adhesion, proliferation, or differentiation. Therefore, it is necessary to adjust the surface properties of PVDF to promote its interaction with biomolecules to improve biocompatibility and hydrophilicity. Studies have shown that arginine-glycine-aspartic acid (RGD) peptide-click-poly(glycidyl methacrylate (PGMA) polymer brush can be grafted to PVDF film surface by atom transfer radical polymerization (ATRP) and click reaction, thereby improving the cell compatibility of the PVDF film for biomedical applications.
