Graphene-like BN/gelatin nanobiocomposites for gas barrier applications.

We report a simple, effective and green way for the fabrication of gelatin-graphene-like BN nanocomposites for gas barrier applications. The reinforcement effect of graphene-like BN on the gelatin properties is discussed. The obtained graphene-like BN nanocomposites show good dispersion in the gelatin matrix and remarkable capability to improve the crystallinity and the barrier properties of gelatin. The barrier properties of gelatin/BN nanocomposites have been enhanced by a factor of 500 at 2 bar compared to a gelatin film without graphene-like BN. The greatly improved performance and the high stability of these nanocomposites may lead exciting materials for their implantation in gas barrier applications.
