Nanocomposites from Regenerated Cellulose and Nanoclay

Enhanced ductility and tensile properties of hybrid montmorillonite/cellulose nanowhiskers reinforced polylactic acid nanocomposites

“…However, when the filler content exceeds 5 phr, the tensile strength dramatically decreases probably due to the aggregation of the filler resulting in stress concentration points for fracture. This result is in agreement with Lee et al [22], where the agglomeration of MMT at filler contents >5 wt.% resulted in a decrease in tensile strength.…”

Study of silane treatment on poly‐lactic acid(PLA)/sepiolite nanocomposite thin films

“…It shows that the addition of silane treated sepiolite influenced the thermal events and crystallinity. 24,25 Moreover, high sepiolite nanoclay content can increase the brittleness of materials, making the matrix stiffer with less plastic in deformation, which are typical characteristics of hard inorganic phase. However, compared with untreated sepiolite, this change was about 9 C in Tg, 1.5 C in T m and 3% from neat PLA to 1.5% sepiolite.…”

“…MMT) (>5 wt %) in polymer can result in its agglomeration resulting in reduced mechanical performance compared to lower content. 24,25 Moreover, high sepiolite nanoclay content can increase the brittleness of materials, making the matrix stiffer with less plastic in deformation, which are typical characteristics of hard inorganic phase. Silane treatment of sepiolite had imparted a good stress transfer from matrix to filler due to the better interaction between sepiolite and PLA which can cause further increment in tensile strength of PLA/sepiolite film.…”
