Hybrid films with excellent oxygen and water vapor barrier properties as efficient anticorrosive coatings.

ABSTRACT: Gas and moisture barrier materials are of crucial importance in various application fields, including food/drug packaging and encapsulation of electronic devices. Herein, a dual-barrier film to gas and water vapor was fabricated by a facile and cost-effective spin-coating of amphiphilic surfactant (Tween 80) modified LDH nanoplatelets (denoted as LDH-80) and polydimethylsiloxane (PDMS). The resultant (LDH-80/PDMS)₁₅ film exhibits low O₂ and H₂O transmission rates with ∼0.701 and ∼0.049 cm³ m^-2 d^-1 atm^-1, respectively, smaller than those for most of the reported barrier materials. The remarkable barrier properties are ascribed to the prolonged diffusion length for gas permeation and improved inorganic-organic inter
