Description
Strong, light polyethylene fibers are usually gel-spun, a process that leans on solvents that must later be removed and that burden the environment. The authors instead melt-spin high-density polyethylene fibers, orient them to raise crystallinity, and finish with ultraviolet cross-linking. Their new step is to blend in POSS, cage-like hybrid nanoparticles, during the melt spinning. Two kinds are used, both carrying double bonds that can join the fiber's network under UV light. The team then measures thermal, structural, and mechanical traits with and without the additive.
Both nanoparticle types raise tensile strength, one by 12.5 percent and the other by 70.8 percent, a gap the authors tie to how evenly each disperses. The better-dispersed vinyl type pushes the finished fiber to 293 megapascals of strength with a modulus of 2.8 gigapascals. The authors present melt spinning plus UV curing as a cleaner route to high-performance fibers.
