A modified polypropylene (PP) feed spacer was produced to control bacterial growth. Vinylbenzyl chloride was reacted with dimethylhexadecylamine to produce an aminated monomer. The resultant product was polymerized by UV polymerization and grafted to the surface of PP. The modified mesh was characterized by mass change and dye testing, followed by Raman and X-ray photoelectron spectroscopies. We have demonstrated antibacterial effectiveness of the polymer against Gram-positive bacteria. Also, scanning electron microscope images before and after the biotest showed a high adsorption of bacteria to the surface. We will discuss our results so far, as well antimicrobial activity of feed spacer in dairy environments.
