Abstract
The dye coated textile fabrics are very much useful in the MRI and bio-imaging applications due to its versatile fluorescence behavior. Based on this concept, in the present investigation the non bio degradable and hydrophobic PVC was chemically modified by two different dyes such as safranine and rose bengal. The chemical modification of PVC can be confirmed by FT-IR, UV–visible, fluorescence, DSC, TGA and SEM analysis. By the structural modification through dyes, PVC was converted into hydrophilic as well as bio-degradable polymer. Under strongly acidic pH, the dye modified PVC becomes water soluble one. The surface morphology analysis confirmed the formation of nano particles in the interface region of hydrophobic PVC and hydrophilic dye molecule and hence suitable for drug releasing applications. Ultrasonic velocity, compressibility and refractive index of the PVC before and after structural modification were determined and the results were critically compared.
