Polyvinylidene fluoride (PVDF) is a semi-crystalline fluoropolymer that combines excellent chemical stability, electrical insulation, mechanical strength, and temperature resistance. PVDF's various crystalline phases (such as the β phase) impart ferroelectric and piezoelectric properties, making it widely used in research and process development for applications such as membrane materials, sensors, battery binders, and functional coatings.
Alfa Chemistry offers research-grade PVDF powder with a purity of ≥99% in a variety of molecular weights (Mw). We accept small-batch orders and custom orders, specifically serving research users and small- to medium-sized project teams.
PVDF is a semicrystalline, high-performance fluoropolymer derived from vinylidene fluoride (VDF, CH2=CF2) monomers. It's molecular backbone contains numerous highly polar C-F bonds. This unique structure endows the material with exceptional chemical resistance, thermal stability, and tunable crystalline phases, making it highly valuable in both academic research and industrial applications. Alfa Chemistry systematically outlines the key advantages and research highlights of PVDF, providing strong support for scientific research and engineering development.

Functional Coatings and Corrosion-Resistant Layers
Composites and Interface Engineering
PVDF is the most commonly used polymer binder in electrode slurries. It forms a stable three-dimensional network with active materials and conductive agents, ensuring the mechanical integrity and electrochemical stability of the electrode coating. It also remains chemically inert under high voltage and electrolyte conditions, making it ideal for interfacial stability and cycle life studies.
PVDF exhibits excellent film-forming and phase-inversion properties. High-porosity, chemically resistant microporous or porous membranes can be prepared via solution casting or non-solvent-induced phase separation (NIPS) techniques. These membranes are used in experimental scenarios such as water treatment, wastewater filtration, gas separation, and bioseparation.
In piezoelectric and energy harvesting material research, electrospun PVDF nanofibers are an important means of achieving a high β-phase content, significantly enhancing piezoelectric and ferroelectric responses. They are widely used in flexible sensors and self-powered devices.
PVDF is also commonly used in the formulation optimization of weather-resistant and anti-corrosion coatings, leveraging its fluoropolymer backbone to achieve excellent UV, chemical, and aging resistance.
In composites and interface engineering, by combining with functional fillers such as carbon nanotubes and graphene, their conductivity, dielectric constant, and interfacial adhesion can be manipulated, providing an ideal matrix for the development of high-performance electronic packaging materials, electromagnetic shielding layers, and structural composites.
Molecular weight is a key parameter of PVDF in terms of processability, mechanical properties, dissolution rate, and final material properties. Common guidelines in research and industry practice include:
Practical Recommendation
For laboratory-grade battery slurries, medium-high molecular weight is preferred. For electrospinning and piezoelectric performance research, low-medium molecular weight is preferred to facilitate dissolution and fiber formation. Molecular weight also affects phase formation (β-phase content) and crystallization behavior.
If necessary, please contact us to request samples for preliminary experiments.
To meet the diverse needs of various research projects, Alfa Chemistry offers flexible PVDF powder customization services, helping researchers quickly obtain materials that meet their experimental requirements.
PVDF is soluble in polar aprotic solvents (such as NMP, DMF, DMAc, and DMSO), with solubility varying with molecular weight and temperature. Laboratory formulations must be performed under strict ventilation and in accordance with solvent safety regulations.
PVDF has a melting point generally around ~160–175°C and is commonly used in melt extrusion, injection molding, or hot press molding. Be aware of the risks of thermal shear and degradation.
Solution concentration, draw rate, and collector speed influence fiber orientation and β-phase conversion and are key parameters for improving piezoelectric performance.
