摘要：

Inspired by the biomaterial nacre, we report a versatile and facile strategy to rugged, flame retardant super-hydrophobic materials by embedding a nacre-like montmorillonite (MMT) based gas barrier layer into hierar-chical epoxy-resins. The well-aligned MMT layer imparted excellent oxygen and water barrier properties that rendered the coating surface water repellent yet protected the substrate materials from fire by suppressing heat and oxygen transfer. The hierarchical epoxy not only provided the robust superhydrophobic structure but offered strong adhesion to MMT layer. After application of ...
