    Nanoclay compatibilization of phase separated polysulfone/polyimide films for oxygen barrier حسب Ammar, Ali

    منشور في 2017
    "…Thermal decomposition (TGA) measurements of PSF/PI films showed a decrease in thermal stability upon adding C30B due to its surfactant modification, while film mechanical tensile modulus properties improved slightly by adding low concentration of C30B (~ 1 mass%), but higher nanoclay loading decreased tensile strength and elongation at break. …"
