Characterization of polylactic acid/microcrystalline cellulose/montmorillonite hybrid composites | Pencirian komposit polilaktik asid/selulosa mikrohablur/ hibrid montmorilonit

The objective of this study is to investigate the effect of montmorillonite (MMT)/microcrystalline cellulose (MCC) hybrid fillers on mechanical properties and morphological characteristics of polylactic acid (PLA) composites. PLA/MMT nanocomposites and PLA/MMT/MCC hybrid composites were prepared by...
