According to foreign media New Atlas, modern adhesives can work wonders in some materials, but they still cannot be applied to many materials. Now, Canadian scientists have come up with a new formula they say could fill the gap, creating new bonds between unlikely materials through a process of cross-linking.
The research was conducted by materials scientists at the University of British Columbia and the University of Victoria, who describe their new adhesive as a "super glue." Key to the new formula is a process called cross-linking. When the team's specially designed molecules are exposed to long-wave UV light, they cause new chemical reactions.
"These molecules can be activated thermally or photochemically to form carbenes that readily insert into polymer carbon-hydrogen bonds, leading to cross-linking," the researchers wrote.
According to the The team says these cross-linked bonds can bond disparate materials together while maintaining impact and corrosion resistance. The technology can be "widely applied" to plastics and synthetic fibers, creating the opportunity to mix and match materials that commercially available glues cannot bond.
Lead researcher Professor Abbas Milani said: "The adhesive has proven particularly effective in high-density polyethylene, which is used in bottles, pipes, geomembranes, wood-plastic composite flooring and Important plastics used in many other applications. In fact, commercially available glues simply cannot be used on these materials, making our findings an impressive basis for a wide range of uses."
Scientists One of the most promising applications envisioned for their new superglue is as an adhesive for more durable clothing. The team is already working with other researchers to develop new types of clothing for first responders, including high-performance body armor with ballistic protection.
Wulf said: “By using this cross-linking technology, we are better able to tightly fuse different types of fabrics together to create the next generation of clothing suitable for extreme environments. With At the same time, the adhesive provides additional material strength to the fabric itself."
The team also believes that the super-strong glue could be used for better medical implants and stronger household pipes. systems, or simply used as additives to enhance the performance of a variety of conventional products.
“Imagine paint that never peels off or waterproof paint that never needs to be resealed,” says Milani. "We're even starting to think about using it as a way to bond many different plastic types together, which is a major challenge in the recycling of plastics and their composites. Making some of our everyday items stronger and less prone to failure "This is real potential, and it's what many chemists and composites engineers are pursuing."
The team's findings were published in the journal Science.
