Reverse osmosis membrane as well as preparation method and application thereof

The invention provides a reverse osmosis membrane as well as a preparation method and application thereof. The preparation method comprises the following steps: (1) carrying out polymerization reaction on polyamine and polyacyl chloride on a support membrane to form a polyamide layer on the support membrane; and (2) reacting the polyamide layer prepared in the step (1) with a benzene series A to obtain the reverse osmosis membrane, the benzene series A is a benzene series containing an amino group, an antibacterial group, a disulfide bond and a phenoxy group. The reverse osmosis membrane provided by the invention has the advantages of high flux, high desalination rate, excellent oxidation resistance, excellent antibacterial property and excellent acid and alkali resistance. 本发明提供一种反渗透膜及其制备方法和应用。所述制备方法包括如下步骤：(1)多元胺和多元酰氯在支撑膜上进行聚合反应，在支撑膜上形成聚酰胺层；(2)将步骤(1)制得的聚酰胺层和苯系物A反应，得到所述反渗透膜；所述苯系物A为含有氨基、抗菌基团、二硫键和苯氧基的苯系物。本发明提供的反渗透膜具有高通量、高脱盐率，以及优异的耐氧化性、抗菌性和耐酸碱性。
