Polylactide/graphene oxide nanosheets/clove essential oil composite films for potential food packaging applications.

Antimicrobial nanopackaging films were developed by incorporating clove essential oil (CLO) (15-30% w/w) and graphene oxide (GO) nanosheets (1% w/w) into polylactide (PLA), suitable for use as food packaging, via solution casting. Addition of CLO into PLA matrix improved the flexibility of the composite films by lowering tensile stress, complex viscosity (η*), and glass transition temperature (T). GO improved the T, η* and lowered the oxygen permeability of the plasticized PLA matrix.
