New description: '· [New technology field] 'This creation is about a filter membrane' especially refers to a filter assembled in a filter for filtering liquid membrane. [Prior Art] Polytetrafluoroethylene (PTFE) is a polymer resin with many special and excellent Φ properties, including excellent electrical insulation properties, wide temperature range, chemical resistance, flame resistance, and weather resistance. Sex, low friction, low surface energy, hydrophobicity, and high mechanical properties, etc., is an engineering plastic with excellent comprehensive performance. Because polytetrafluoroethylene (PTFE) has low surface energy and hydrophobicity, it is widely used in waterproof materials, but its strong hydrophobicity limits its application of liquid filtration, making it difficult to be wet or retained by aqueous fluids. Wet state. In the past, when a filter membrane made of polytetrafluoroethylene was used for liquid filtration, it was first pre-wet with a low-carbon chain alcohol, and then the filter membrane was placed in a flowing liquid to remove particles from the liquid. , solute or microorganism. However, due to the strong hydrophobicity of the filter membrane, the water flow channel becomes smaller and smaller, and the hydrophilicity gradually disappears. At this time, the membrane pores of the filtration membrane are re-swelled with low-carbon alcohols. In view of this, how to maintain the hydrophilicity of the filter film during transportation or use without the need of pre-swelling treatment is a goal that the industry needs to develop. [New content] In order to overcome the above disadvantages, the present invention provides a filter membrane comprising a hydrophilic layer composed of a fluorine-containing body and a hydrophilic polymer material, the body having a first surface and a first surface, and The first surface and the second surface are formed into a plurality of holes, and the hydrophilic layer is formed on the first surface, the second surface and the pores so that the contact angle of the filtration membrane is 9 degrees.

When the channel is fixed, the hydrophilicity of the filter membrane will not be reduced due to time, so it can be stored in a dry state without pre-swelling treatment during the handling process or construction site, and can maintain its hydrophilicity during dry storage. And direct water can be filtered immediately. The present invention further provides a filter having a filter membrane comprising a filter substrate, a support material, and a filter membrane. The filter substrate has a flow path structure and is formed on a surface of the filter substrate. The aforementioned support is formed on the surface of the substrate and covers the flow path structure.

Zhan is formed on the first surface, the second surface and the hole, so that the contact angle of the transition film is $9, and the ruthenium film is formed on the support material, so that the support material is interposed between the fine and the slab. Therefore, the purpose of the present invention is to provide a filter having a ruthenium film, the filter is passed through; after the film is hydrophilized, the water passage formed by the hole of the filter itself is fixed. It doesn't time to shout the hydrophilicity of _, so it is secretly stored in the dry vein. It doesn't need to be handled during the handling process or the guardian of the woman, and it is also secretive in the dry county. The water is filtered.
