A better understanding of the polymeric irradiation using physico-electrochemical characteristics

Poly(ester-urethane) urea (PEUU) based on ethanolamine as a chain extender contain hydroxyl and amino groups was chemically synthesized using 1,1'-methylenebis(4-isocyanatobenzene) MDI diisocyanates, castor oil. One step polymerization procedure has been used to complete the PEUU formation this polymeric target irradiated with different doses (100, 250, 400, 600 kGy) of gamma rays. A full physico-electrochemical characterization package performed solid surfaces, radiated vs. non-irradiated, for better understanding structure changes. To that end, Fourier transform infrared spectroscopy (FTIR), morphological features were characterized by scanning electron microscope (SEM). Thermal stability investigated differential calorimetry (DSC), while crystallinity electrochemical properties explored X-ray diffraction (XRD), cyclic voltammetry (CV), respectively. Eventually, swelling, crosslinking density, mechanical strength, water absorption, contact angle measurements discussed. Ultimately, density discovered be dependent. Worth mentioning here, kind study is recommended protocol could applied other targets exposed electromagnetic radiations.
