Pusan National University researchers unveil game-changing UV-fueled shape-shifting and shape-fixing smart materials
Magnetic micropillar arrays consist of tiny, vertical pin-shaped structures, arranged in a grid-like pattern. These micropillars can change their shape to a pre-programmed geometry when exposed to a magnetic field. They are made from magnetically responsive composites, comprising rubbery polymers like polydimethylsiloxane (PDMS) embedded with magnetic particles. These composites can change their shape and recover repeatedly without any deterioration.
Unfortunately, conventional magnetic micropillar arrays can only hold their changed shape temporarily while the magnetic field is being applied. Previous studies have explored various approaches to address this issue, including water-soluble ...
