Estimation the Properties of Polymer Matrix Reinforced with Plants Extract Used for Medical Fluid Bags

Abstract The utilize of polyvinyl chloride in the manufacturing of blood bags responsible for preserving blood. It attains an extensive range of performance and processing requirements such as flexibility, transparency, physical, antibacterial and non-hemolysis properties. So, in the present flax-seed gel was incorporated in PVC matrix at various concentration (1, 2 and 3) %. Then wheat extract was added to samples has better properties in two percentage (0.5 and 1) %. The obtained results show, a significant change in the properties of the composite produce, where the tensile strength increased with increasing concentration of extract from flax seed gel, but it decreased when wheat extract was added, and when both extracts were added, the inhibition zone increased against bacterial activity for two types of bacteria (S. aureus and C. albicans). Also, the ability to absorb water and wettability increased with increasing concentration of plant extracts. On the other hand, the transparency decreased with increasing concentration of flaxseed gel, but when wheat gel was added to it increase of transparency. All samples were non-hemolytic in hemolysis test.
