| titleOfInvention | It is a kind of using bifunctional vinyl compound as polyvinyl alcohol film of crosslinking agent and preparation method thereof |
| abstract | The present invention provides a kind of using bifunctional vinyl compound as the polyvinyl alcohol film of crosslinking agent, it is characterised in that：Covalent bond is formed after the polyvinyl alcohol mesomethylene carbon dehydrogenation with bifunctional vinyl compound to crosslink.The method of the present invention simple possible, easily operated, the crosslinking PVA composite membranes of preparation have perfect infiltration evaporation membrane structure, have good selective penetrated property, and stable chemical performance to water, are suitable for prolonged lock out operation；Both the excessive swelling for having overcome film in turn ensures that the hydrophily of film, film have higher permeation flux and separation factor. |
