flag Cornell researchers created the darkest fabric ever, reflecting 0.13% of light, using bird-inspired nanofibers.

flag Researchers at Cornell University have developed the darkest fabric ever made, reflecting just 0.13% of light, inspired by riflebird feathers. flag Using polydopamine dye and plasma etching to create light-trapping nanofibrils, the team produced a wearable, scalable material that stays ultrablack across a 120-degree angle. flag The fabric, effective on wool, silk, and cotton, could improve solar energy absorption, enable advanced camouflage, and advance fashion design. flag Led by Assistant Professor Larissa Shepherd, the team has applied for a provisional patent and is pursuing commercialization through Cornell’s innovation programs.
