Rational design of active packaging films based on polyaniline-coated polymethyl methacrylate/nanocellulose composites

Nanocomposites of polymethyl methacrylate (PMMA)/cellulose nanocrystals (CNC) have been developed through physical mixing of different ratios of CNC with dissolved PMMA. Solvent exchange method has been carried out in order to increase the dispersion of CNC in the polymer matrix. The obtained composite films showed high transparency. Moreover, its barrier properties against water vapor were significantly increased. The nanocomposite films were...
