Medical-grade Polyvinyl Chloride Modified with Crystal Violet and Montmorillonite

چکیده
Bacterial colonization of polymeric medical aids causing so-called nosocomial infections is one of the main problems linked with the extensive use of polymeric devices in clinical applications. In this study, the properties of medical-grade polyvinyl chloride were modified by incorporating crystal violet into its bulk structure. Sodium montmorillonite was used as a carrier for the crystal violet in the mixture and was expected to effectively control the release rate of the crystal violet to and from the surface of the polyvinyl chloride. The extent of release of the crystal violet from such composites was determined using various leaching media.
