The interaction in sorbitol-plasticized starch bionanocomposites via positron annihilation lifetime spectroscopy and small angle X-ray scattering

Liu, Huihua; Chaudhary, Deeptangshu; Roberts, Jason; Weed, Ryan; Sullivan, James; Buckman, Stephen


We investigated the free volume variations (size and distribution) within sorbitol plasticized high amylose bionanocomposites of different formula where the interactions among sorbitol, amylose and hydrophilic montmorillonite nanoclay (MMT) modified the crystallinity and therefore, the free volume of the matrix. Positron Annihilation Lifetime Spectroscopy (PALS) is a useful technique to monitor the changes of free volume within the polymer matrix - due to polymer-plasticizer or polymer-polymer...[Show more]
