ABSTRACT:
A polyvinylidene difluoride structure with a critical surface energy of at least about 80 dynes/cm and a method of making such a structure comprising the steps of contacting a polyvinylidene difluoride structure with an alkalized solution, such as potassium hydroxide, to form activated sites on the surface of the structure; rinsing the activated structure to remove residual alkali; contacting the rinsed, activated structure with a solution of a polymerization initiator, such as potassium peroxydisulfate, and a polymerizable vinylic monomer, such as acrylic acid; and polymerizing and grafting the monomer to the activated structure to form a polyvinylidene difluoride structure with a critical surface energy of at least about 80 dynes/cm.
