Along with improving its properties, it also limits stereocomplex formation through solution and stereocomplex memory. The graft structure and presence of nanoparticles have a synergetic effect, improving the stereocomplex formation and its memory. The bio-stereocomplex-nanocomposite materials are generated by stereocomplexation of polylactide-graft-acetylated cellulosic nanowhiskers in thes solution. The graft structure containing well-distributed acetylated cellulose nanowhiskers results in unusual stereocomplexation in the solution and influences the stereocomplex memory of the bio-stereocomplex-nanocomposite materials. Perfect stereocomplexes are easily obtained in a relatively short mixing time (5 min) from various solution concentrations up to 20 % (w/v). The bio-stereocomplex-nanocomposites have excellent stereocomplex memory to re-form the stereocomplex after melting, which is the main limitation of stereocomplex materials in industrial processes. This fully bio-based material is a potential ecofriendly candidate for the future.
