Description
Summary:This review relates the free volume properties and the morphology to the mass transport coefficients of polymer nanocomposites. Direct, utilising the method of Positron Annihilation Life-time Spectroscopy (PALS), or indirect measurements of the free volume in the nanocomposites are discussed and the influence of spherical or anisometric nanoparticles on its properties is examined. [Display omitted] ► The free volume of polymers is altered by incorporation of nanoparticles. ► Free volume and tortuosity determine mass transport in polymer nanocomposites. ► Free volume hole size distribution affects the transport properties.
