Description
Jiajia Niu and co-authors build a faster way to screen sampling materials in a 2026 study. Solid-phase microextraction pulls target chemicals onto a coated fiber, and picking the right coating is slow trial and error. Their target was vinyl acetate, a chemical used in food contact plastics, which lacks a standard migration test.
They prepared thirteen porous framework materials and ranked them with a vapor sorption method that tracks how much vapor a solid takes up. That ranking matched the fibers' real extraction performance exactly, and the two measures correlated strongly. Computer modeling of surface charge explained why two materials bound best. The winner was then used to measure vinyl acetate migration from several food contact copolymer samples.
