Cross-Linking Expertise Tightly Binds The place Industrial Glues Can’t
With lots of the merchandise we use day by day held collectively by adhesives, researchers from UBC’s Okanagan campus and the College of Victoria hope to make all the things from protecting clothes to medical implants and residential plumbing stronger and extra corrosion resistant because of a newly-developed ‘hyper glue’ method.

The staff of chemists and composite supplies researchers found a broadly relevant methodology of bonding plastics and artificial fibers on the molecular stage in a process known as cross-linking. The cross-linking takes impact when the adhesive is uncovered to warmth or long-wave UV gentle making robust connections which might be each impact-resistant and corrosion-resistant. Even with a minimal quantity of cross-linking, the supplies are tightly bonded.
“It turns out the adhesive is particularly effective in high-density polyethylene, which is an important plastic used in bottles, piping, geomembranes, plastic lumber and many other applications,” says Professor Abbas Milani, director of UBC’s Supplies and Manufacturing Analysis Institute, and the lead researcher on the Okanagan node of the Composite Analysis Community. “In fact, commercially available glues didn’t work at all on these materials, making our discovery an impressive foundation for a wide range of important uses.”
UVic Natural Chemistry Professor Jeremy Wulff, whose staff led the design of the brand new class of cross-linking supplies, collaborated with the UBC Survive and Thrive Utilized Analysis to discover the way it carried out in real-world purposes.
“The UBC STAR team was able put the material through its paces and test its viability in some incredible applications, including ballistic protection for first responders,” says Wulff.
The invention, he says, is already enjoying an necessary function within the Consolation-Optimized Supplies for Operational Resilience, Thermal-transport and Survivability (COMFORTS) community, a staff of researchers from UBC, UVic and the College of Alberta who’re collaborating to create high-performance physique armor.
“By using this cross-linking technology, we’re better able to strongly fuse together different layers of fabric types to create the next generation of clothing for extreme environments,” says Wulff. “At the same time, the cross-linker provides additional material strength to the fabric itself.”
Milani is fast to level out that an extremely robust bonding agent is only the start of what it might do.
“Imagine paints that never peel or waterproof coatings that never need to be resealed,” says Milani. “We’re even starting to think about using it as a way to bond lots of different plastic types together, which is a major challenge in the recycling of plastics and their composites.”
“There is real potential to make some of our everyday items stronger and less prone to failure, which is what many chemists and composite materials engineers strive for.”
The analysis was published recently within the journal Science and was co-sponsored by Victoria-based firm Epic Ventures and Mitacs Canada.
