Is pvdf an organic film or a water film?

Organic film: Organic film refers to thin film materials made from organic polymers (usually compounds of carbon and hydrogen elements).

These films can have different physical and chemical properties, depending on the type of organic polymer used and the preparation method.

Organic membranes are commonly used in separation, filtration, membrane reactors, electronic devices, medical equipment and many other fields.

They can have different characteristics such as microporous structure, chemical stability, electrical properties, etc., depending on the application requirements.

Water film: Water film usually refers to a film or coating containing water, in which water is one of the important components.

These films may include liquid water or hydrated compounds.

The properties and applications of water films vary depending on the specific chemical composition and application field.

Water film can be used for water treatment, waterproof, moisture-proof, wetting coating and other applications.

For example, some building materials may have waterproof properties, where water-containing materials are used to improve the water resistance of the surface.

Properties and composition of PVDF

The main component of PVDF filter membrane is PVDF polymer, which is usually prepared by polymerized PVDF resin.

The preparation process of the filter membrane usually involves the dissolution of the polymer, the formation of the membrane (for example, casting, extrusion or spin coating), and then a curing process is required to remove the residual organic solvent to ensure the stability of the membrane.

The pore structure of the membrane can be controlled by adjusting the preparation conditions to meet different filtration and separation requirements.
