Hydrophilic, heat stable, low protein binding surface modification of PVDF membranes

  • John Charkoudian (a1), Alex Xenopoulos (a1) and John Lynch (a1)


Protein binding studies reveal increased levels of protein adsorbed to thermally treated poly-acrylamide-modified PVDF microporous membranes in comparison to polyacrylate-modified membranes. Application of XPS, ToF-SIMS, densitometry and μthermal AFM indicate poly-acryamide-PVDF mixing as the primary cause of the increased protein binding.
