Scientists create 'super ice' that is ten times stronger and far harder to shatter
Ice is cheap, abundant and surprisingly strong. But it has one major weakness: Cracks can race through it, causing it to shatter without warning. Now, scientists have developed a new material that could overcome that problem. Called BioPykrete, the reinforced ice is about 10 times stronger than ordinary ice and can absorb roughly 70 times more energy before breaking.
Scientists have engineered a new material called BioPykrete that is ten times stronger and more resilient than traditional ice. The key to its remarkable properties lies in the combination of ice with cellulose nanocrystals and a specially designed protein. The cellulose network forms a three-dimensional structure around microscopic ice particles, creating a robust framework.
This structure, when frozen, significantly enhances the material's strength and energy absorption capacity. Unlike ordinary ice, which can shatter abruptly, BioPykrete deforms gradually, absorbing up to 70 times more energy before failing. The molecular glue, a protein with specific binding domains for both ice and cellulose, effectively anchors the cellulose network to the ice, impeding the spread of cracks and preventing widespread structural failure.
While promising, BioPykrete is still an experimental material, requiring further research to understand its long-term performance, durability under cyclic conditions, and potential applications in extreme cold environments.
