Cellulose Nanocrystal Compound Stronger Than Bone and Tougher Than Aluminum Aims to Replace Plastic.
In a groundbreaking development, researchers at the Massachusetts Institute of Technology (MIT) have created a novel plant-based material that has the potential to replace traditional plastics. This innovative material, made from cellulose extracted from trees and a synthetic polymer, surpasses the strength of some types of bone and is harder than typical aluminum alloys. The team behind the project believes this discovery could pave the way for more sustainable plastics in the future.
The material, derived from cellulose nanocrystals (CNCs) found in the cell walls of trees, is stiffer and stronger than Kevlar at the nanoscale. MIT scientists combined off-the-shelf CNC with a synthetic liquid polymer, forming a gel that can contain a remarkable 60-90% CNC. To prevent clumping of the nanocrystals, researchers utilized an ultrasonic probe, breaking them free and enabling robust bonding with other polymer molecules. These strong bonds pervade the material, creating a composite substance stronger than some bones and harder than standard aluminum alloys.
Although the material experiences shrinkage during the drying process, limiting its use for large-scale printing, researchers are optimistic about overcoming this challenge. If successful, the potential applications of this cellulose composite material are vast. Dreaming big, the researchers envision replacing a substantial fraction of plastics with cellulose composites, offering a sustainable alternative to conventional plastic products.
The implications of this discovery for the environment and the plastic industry are immense. If the material can be produced on a large scale and at an affordable cost, it could significantly reduce our reliance on fossil fuel-based plastics. Furthermore, this plant-based innovation could play a pivotal role in reducing plastic waste, one of the most pressing environmental challenges of our time.
The news of MIT’s breakthrough has been met with widespread enthusiasm and anticipation. Environmentalists, scientists, and industries are closely watching this development, recognizing its potential to transform the landscape of materials science and contribute significantly to a more sustainable future.
