| titleOfInvention | Aromatic polyamide composite reverse osmosis membrane grafted with fluorocarbon material and aminoglycoside antibiotic and preparation method thereof |
| abstract | The invention relates to an aromatic polyamide composite reverse osmosis membrane grafted with fluorocarbon materials and aminoglycoside antibiotics and a preparation method thereof; preparing a fluorocarbon material with the molar concentration of 0.05-0.2 mol/L and a bromo-3, 4-dimethoxyacetophenone initiator solution with the molar concentration of 0.001-0.1 mol/L; immersing the surface of the nascent reverse osmosis membrane in a solution, taking out the membrane, and initiating grafting under an ultraviolet lamp; and immersing the surface of the reverse osmosis membrane in an aminoglycoside antibiotic solution, and finally drying the membrane to compound the reverse osmosis membrane. The invention keeps the permeability selectivity of the unmodified aromatic polyamide composite reverse osmosis membrane; the method has the characteristics of small flux attenuation degree of the low-surface-energy material modified membrane and high flux recovery rate of the hydrophilic material modified membrane. After the aromatic polyamide composite reverse osmosis membrane grafted with the fluorocarbon material and the aminoglycoside antibiotic is contacted with bacillus subtilis or escherichia coli, the antibacterial property is excellent, and the aromatic polyamide composite reverse osmosis membrane has triple anti-pollution functions. |
