Defects such as pinholes, cracks and grain boundaries are common in thin oxide barrier films when fabricated onto plastic substrates. These defects cause a 'pore effect', where oxygen and water molecules are able to seep through and penetrate the plastic barrier. TBF has taken an innovative approach to resolve the ?pore effect? by literally plugging the defects in the barrier oxide films using nanoparticles.
