| titleOfInvention | Preparation method of mesoporous hydrophobic silicon modified polyvinylidene fluoride flat microfiltration membrane |
| abstract | The invention discloses a preparation method of a mesoporous hydrophobic silicon modified polyvinylidene fluoride flat microfiltration membrane, which utilizes the hydrophobic and oleophobic properties of mesoporous hydrophobic silicon to ensure that the surface of the polyvinylidene fluoride flat microfiltration membrane has certain hydrophobic groups, can repel the adsorption of hydrophilic pollutants and oil substances in the running process of the membrane, prevent the permeation of pollutants with low surface tension and improve the anti-pollution performance of the flat microfiltration membrane, and simultaneously, because a high-thickness and large-aperture supporting woven fabric and a pretreatment method of the woven fabric are selected, the microfiltration membrane is easy to form macropores in the membrane forming process so as to keep high flux and high anti-stripping strength. |
