Fabricating 3A Optical Films via Transfer Printing from a Nickel Nanocone Array Template

Nanostructured surfaces are fundamental for the development of various functional films. Nanoimprint technology enables the transfer of patterns from templates with micro-nano structures onto various substrates to enable advanced functionalities. However, developing practical large-area periodic templates and achieving high-performance thin layers through imprinting have been challenging. This study presents a method for creating nickel nanocone arrays (NCAs) through electrodeposition as nanoimprint templates. By transfer printing optical resins with corresponding nanostructured surfaces using these templates, optical films with anti-glare (AG) functionality are produced. Additionally, anti-fingerprint (AF) resin with a specific thickness is coated on the surface of the optical films to achieve both anti-reflective (AR) and AF functionalities. The 3A optical films demonstrate exceptional properties, characterized by high hydrophobicity, low reflectivity, high transmittance, and desirable haze. This showcases the promising application potential of this innovative technology in the field of 3A optical films as well as photovoltaic panel applications.
