A polyelectrolyte-surfactant complex as support layer for membrane functionalization

Mostrar todas las versiones(2)

A polyelectrolyte-surfactant complex, polyallylamine-dodecylsulfate system, is presented as an alternative method for the modification of membranes. Due its chemical structure, the complex, once casted on a surface, is highly stable in aqueous solutions. This allows modifying with the same method di...
