UBC forestry researchers have created a new super-black material that absorbs almost all light. From left, Dengcheng Feng, Kenny Cheng, Dr. Philip Evans and Sara Xu. \u00a9 UBC Forestry\/Ally Penders<\/figcaption><\/figure><\/div>\n\n\n

Thanks to an accidental discovery, researchers at the University of British Columbia have created a new super-black material that absorbs almost all light, opening potential applications in fine jewelry, solar cells and precision optical devices.\u00a0<\/strong><\/p>\n\n\n\n

Professor Philip Evans and PhD student Kenny Cheng were experimenting with high-energy plasma to make wood more water-repellent. However, when they applied the technique to the cut ends of wood cells, the surfaces turned extremely black. <\/p>\n\n\n\n

Measurements by Texas A&M University\u2019s department of physics and astronomy confirmed that the material reflected less than one per cent of visible light, absorbing almost all the light that struck it. <\/p>\n\n\n\n

Instead of discarding this accidental finding, the team decided to shift their focus to designing super-black materials, contributing a new approach to the search for the darkest materials on Earth.<\/p>\n\n\n\n

\n

\u201cUltra-black or super-black material can absorb more than 99 per cent of the light that strikes it \u2013 significantly more so than normal black paint, which absorbs about 97.5 per cent of light,\u201d explained Dr. Evans<\/strong>, a professor in the faculty of forestry<\/strong> and BC Leadership Chair in Advanced Forest Products Manufacturing Technology.<\/p>\n<\/blockquote>\n\n\n

The UBC-developed\u00a0super-black wood\u00a0inherently prevents light from escaping rather than depending on black pigments.\u00a0\u00a9 UBC Forestry\/Ally Penders<\/figcaption><\/figure><\/div>\n\n\n

Super-black materials are increasingly sought after in astronomy, where ultra-black coatings on devices help reduce stray light and improve image clarity. Super-black coatings can enhance the efficiency of solar cells. They are also used in making art pieces and luxury consumer items like watches.<\/p>\n\n\n\n

The researchers have developed prototype commercial products using their super-black wood, initially focusing on watches and jewelry, with plans to explore other commercial applications in the future.<\/p>\n\n\n\n

Wonder wood<\/h3>\n\n\n\n

The team named and trademarked their discovery Nxylon (niks-uh-lon), after Nyx, the Greek goddess of the night, and xylon, the Greek word for wood. <\/p>\n\n\n\n

Most surprisingly, Nxylon remains black even when coated with an alloy, such as the gold coating applied to the wood to make it electrically conductive enough to be viewed and studied using an electron microscope. This is because Nxylon\u2019s structure inherently prevents light from escaping rather than depending on black pigments.<\/p>\n\n\n\n

The UBC team have demonstrated that Nxylon can replace expensive and rare black woods like ebony and rosewood for watch faces, and it can be used in jewelry to replace the black gemstone onyx.<\/p>\n\n\n

\n

\u201cNxylon\u2019s composition combines the benefits of natural materials with unique structural features, making it lightweight, stiff and easy to cut into intricate shapes,\u201d said Dr. Evans<\/strong>.<\/p>\n<\/blockquote>\n\n\n\n

Made from basswood, a tree widely found in North America and valued for hand carving, boxes, shutters and musical instruments, Nxylon can also use other types of wood such as European lime wood.<\/p>\n\n\n\n

Breathing new life into forestry<\/h3>\n\n\n\n

Dr. Evans and his colleagues plan to launch a startup, Nxylon Corporation of Canada, to scale up applications of Nxylon in collaboration with jewellers, artists and tech product designers. They also plan to develop a commercial-scale plasma reactor to produce larger super-black wood samples suitable for non-reflective ceiling and wall tiles. <\/p>\n\n\n\n

\n

\u201cNxylon can be made from sustainable and renewable materials widely found in North America and Europe, leading to new applications for wood. The wood industry in B.C. is often seen as a sunset industry focused on commodity products\u2014our research demonstrates its great untapped potential,\u201d said Dr. Evans<\/strong>.<\/p>\n<\/blockquote>\n\n\n\n
