Abstract: Poly(lactic acid)/organo-montmorillonite (PLA/OMMT) nanocomposite films were
prepared through solution intercalation using dichloromethane as solvent. X-ray diffraction
indicated that organo-montmorillonite (OMMT) was well intercalated and the interlayer spacing
d increased by 0.94-1.47 nm. Transmission Electron Microscopy showed that a majority of OMMT
was fully exfoliated and uniformly dispersed in the PLA matrix at low filler loading, whereas more
intercalated tactoids and aggregates of OMMT existed at high loading. The crystallinity of PLA
was hardly changed with the addition of OMMT. Additionally, CO2 permeability and water vapor
transmission rate of the composite films were reduced with increasing content of OMMT. At 5
wt% OMMT loading, CO2 permeability and water vapor transmission rate were reduced by 75.8%
and 23.9%, respectively. The tensile strength (TS) and Young's modulus of the PLA/OMMT
nanocomposites were first enhanced, and then decreased with increasing content of OMMT.
Compared with pure PLA, a 83.8% increase in the Young's modulus and a 76.0% improvement in
TS were obtained with the addition of 3 wt% OMMT. © 2013 Taylor & Francis Group, LLC.
