| titleOfInvention | Polytetrafluoroethylene superfine hollow fiber membrane |
| abstract | The invention provides a polytetrafluoroethylene hollow fiber membrane which comprises a polytetrafluoroethylene material body, wherein polytetrafluoroethylene is fibrous, the diameter of the fiber is 30-200 nm, the body is provided with a pore cavity with the pore diameter of 10-1000 nm and a cavity wall formed by surrounding the pore cavity in a three-dimensional space, the pore cavity is uniformly distributed, all the pore cavities are communicated in a three-dimensional mode, the pore cavity is uniformly distributed on the porous material in any unit volume, the porosity is more than 65%, and the light transmittance is more than 45%. The invention provides a specific and definite measuring mode for the pore space distribution uniformity of the polytetrafluoroethylene hollow fiber membrane, and defines the pore distribution uniformity of the porous material and the multi-level structure thereof under the scale of small unit level volume, and the porous structure is highly uniform, thereby ensuring the uniformity and consistency of all performances of the porous material. |
