Abstract

Anti-reflective polystyrene nanopillar arrays were fabricated by the process of hot embossing where it utilizes the nickel coated anodised aluminium oxide template. Electroless plating being a catalytic method of plating uniformly coats the membrane which increases its strength. The supporting layer of nickel makes AAO template suitable to be used as a mould multiple times. Highly conformal nanopillars of average diameter 400nm and length 30 μm to 50μm were fabricated on the area of ⁓5cm2. Hot embossing process ensures repeatability with precision and high throughput. The enhanced light entrapping is attributed to the multiple internal reflection in the nanopillars of high aspect ratio.
