Laser micromachining of magnetoactive elastomers as enabling technology for magnetoresponsive surfaces
Gaia Kravanja, Inna A. Belyaeva, Luka Hribar, Irena Drevenšek Olenik, Mikhail Shamonin, Matija Jezeršek
Izvirni znanstveni članek
Oznake: magnetoaktivni elastomeri;omočljivost;lasersko strukturiranje;magnetoactive elastomers;wettability;laser structuring;
A simple method for structuring of the surface of a magnetoactive elastomer (MAE) on the tens of micrometers scale, which capabilities extend beyond conventional mold-based polymer casting, is reported. The method relies on the ablation of the material by absorption of nanosecond infrared pulses fro ...
