Cornell Unveils Wearable Ultrablack Wool With Record 0.13% Reflectance

Cornell's two-step, biomimetic process pairs polydopamine dyeing with plasma-etched nanofibrils to deliver a scalable ultrablack textile.

Overview

  • The Nature Communications study reports the fabric maintains ultrablack appearance across a 120-degree viewing span.
  • The design draws on the magnificent riflebird’s melanin-rich, light-trapping feather structures studied with the Cornell Lab of Ornithology.
  • The method was demonstrated on merino wool and is reported as applicable to other natural fibers such as cotton and silk.
  • The team has applied for provisional patent protection through Cornell’s Center for Technology Licensing and is exploring commercialization for uses including solar-thermal and thermo-regulating camouflage.
  • A strapless dress by student designer Zoe Alvarez showcased the material, with image adjustments confirming its persistently deep black appearance.
