Our proprietary Advanced Surface Nanoforming (ASN™) process creates precise patterns with features in sizes ranging from tens of microns down to tens of nanometers directly into a substrate’s surface. Substrates include polycarbonate, Zeonor and Topas cyclic olefins, PMMA (acrylic), CAB/CAP (cellulose acetates), and more. Because of its reduced temperature processing requirements, ASN eliminates thermal substrate distortion and temperature cycling of patterning templates typical of thermal imprinting. And unlike UV nanoimprinting, ASN also eliminates potential delamination and radiation source issues. Because there is no substrate-polymer interface, adhesion failure and refractive index mismatching are eliminated.

ASN patterning is the process of choice for creating micron to nanometer size structures when failure-proof adhesion is required, whether on thin or thick substrates, when elevated temperatures must be avoided, or for applications requiring the ultimate in optical clarity.

Benefits of Advanced Surface Nanoforming

  • Enables monolithic patterned films
  • Offers single or dual-sided patterning
  • Lower cost compared to other techniques
  • Eliminates optical effects arising from substrate-polymer interface
  • Eliminates delamination of pattern layer from substrate
  • Compatible with temperature-sensitive substrates
  • Used on a range of film substrates, including ultra-clear cyclic olefins (COC), polycarbonates, PMMA, polyurethanes, etc.
