Background:

Antireflective surfaces are vital for photonic systems but traditionally limited to rigid, flat designs.
Developing effective antireflective strategies for deformable geometries remains a challenge.

Purpose of the Study:

To present a novel antireflective strategy for deformable device geometries.
To combine superior optical performance with mechanical robustness in a single solution.

Main Methods:

Utilizing block copolymer self-assembly to embed bioinspired nanohole arrays into a transparent polymer.
Employing simulation studies to validate optical performance and analyze refractive index gradients.

Main Results:

Achieved over 70% reduction in light reflection across the visible spectrum compared to nonpatterned surfaces.
Demonstrated high mechanical resilience due to interconnected nanostructures dissipating stress.
Exhibited multifunctionality, including self-cleaning properties, attributed to surface hydrophobicity.

Conclusions:

The developed nanoengineered surface offers a promising solution for next-generation optical and optoelectronic systems with complex, deformable designs.
The strategy provides a straightforward method for creating robust, high-performance antireflective surfaces on flexible materials.
