Influence of dynamic crosslinking on the morphology, crystallization, and dynamic mechanical properties of PA6,12 EVA blends
Bondan, Fabricio; Ernzen, Juliano; Amalvy, Javier; Machado, Ana; De Nardi Martins, Johnny; Bianchi, Otavio (2016)This study investigated the effect of dynamic crosslinking of polyamide 6,12 and random copolymers of ethylene and vinyl acetate blends (PA6,12/EVA) on the morphology, crystallinity, and dynamic mechanical properties. The ... -
Morphology and properties of neutralized chitosan-cellulosenanocrystals biocomposite films
Corsello, Flavia Anahí; Bolla, Patricia Araceli; Anbinder, Pablo; Serradell, María de los Ángeles; Amalvy, Javier; Peruzzo, Pablo (2016)Chitosan/cellulose nanocrystals (CH-CN) films were obtained by casting of dispersions, and treated with NaOH for neutralization proposes. The composition of films was varied from 1 to 10 wt.% of CN. Changes in the morphology ... -
