| titleOfInvention | Hydrophilic single-layer porous membrane and preparation method and application thereof |
| abstract | The invention discloses a hydrophilic single-layer porous membrane and a preparation method and application thereof, belonging to the technical field of functional material preparation. The method prepares a hydrophilic single-layer polymer porous membrane by preparing a membrane casting solution, scraping the membrane and utilizing a phase inversion method, and controls to prepare asymmetric micro-nano holes with different pore sizes on the opposite surfaces of the single-layer polymer membrane by changing the initial concentration of the membrane casting solution, the thickness of the membrane scraping solution, the composition of a phase inversion solvent and the proportion of a mixed phase inversion solvent so as to realize intelligent control on different permeation states of the liquid. The preparation method of the hydrophilic single-layer porous membrane disclosed by the invention is simple and easy to implement, the thickness, the porosity and the pore size of the prepared porous membrane are easy to control, the cost is low, the preparation method is environment-friendly, safe and reliable, the industrial scale production is easy, and the hydrophilic single-layer porous membrane can be well applied to the fields of dressing or functional textiles for liquid one-way permeation and rapid drying of wounds and directional transportation. |
