Investigation On Miscibility Behaviors Of Elastin-Like Polypentapeptide Blends With Polyvinyl Alcohol In Aqueous And Solid State

The polypentapeptide of elastin, poly(GVGVP) has shown remarkable properties and have great potential for biomedical applications. To explore its applications further, the miscibility behaviors of poly(vinyl alcohol) (PVA)/poly(GVGVP) blends have been explored in a very broad composition range. The miscibility behaviors of these blends have been investigated in both solution and solid state using various analytical techniques, including ultrasonic velocity, density, refractive index (RI) and viscosity techniques at 25 degrees C. The results confirmed the miscibility of the blend up to 40% of the polypeptide. This was further supported by Fourier transform infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). (C) 2016 Wiley Periodicals, Inc.
