A highly durable silica/polyimide superhydrophobic nanocomposite film with excellent thermal stability and abrasion-resistant performance

Abstract

Superhydrophobic self-cleaning materials are widely applicable in many areas, but the low durability of superhydrophobicity is always a major obstacle for real-world applications. Here we propose a rather simple way to increase durability. We combine electrospinning and polyimides with nano-sized silica to create a durable self-cleaning film. Such films present strong resistance to heat and abrasion, along with thermal insulation. The delicate lotus effect can also be tough and durable.
