CHARACTERIZATION AND SOME PROPERTIES OF IRRADIATED AND GRAFTED NYLON 6 FILMS

The grafting of hydrophilic monomers such as acrylic acid (AAc), acrylamide (AAm), and its mixture onto hydrophobic polymer such as Nylon 6 (Ny 6) films results in graft copolymers exhibiting hydrophilic properties as well as good swelling behavior. It was found that the variation of the experimenta...

Description
Summary:The grafting of hydrophilic monomers such as acrylic acid (AAc), acrylamide (AAm), and its mixture onto hydrophobic polymer such as Nylon 6 (Ny 6) films results in graft copolymers exhibiting hydrophilic properties as well as good swelling behavior. It was found that the variation of the experimental parameters of the grafting process has no effect on the hydrophilic properties of the film. The water uptake appears to reflect predominantly the percentage of PAAm and or PAAc in the membranes. The alkali-treated films possess higher hydrophilic properties than the alkali untreated ones. Also, it was found that the moisture regain of the grafted Ny 6 has a higher value than the irradiated ones. The thermal and mechanical properties of the grafted films were also investigated. The prepared membranes of Nylon 6 grafted with acrylic acid, acrylamide, and their comonomers can be successfully used as cation-exchange membranes, which are suitable for different practical applications, especially for the separation of some selected heavy metals and radioactive waste in wastewater.
