Tunable surface roughness and wettability of a soft magnetoactive elastomer
Gašper Glavan, Peter Salamon, Inna A. Belyaeva, Mikhail Shamonin, Irena Drevenšek Olenik
Izvirni znanstveni članek
Oznake: materiali;polimeri;magnetoaktivni elastomeri;magnetne lastnosti;optične lastnosti;materials;polymers;magnetoactive elastomers;magnetic properties;optical properties;
Surface topographical modifications of a soft magnetoactive elastomer (MAE) in response to variable applied magnetic field are investigated. The analysis is performed in situ and is based on optical microscopy, spread optical reflection and optical profilometry measurements. Optical profilometry ana ...

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 ...

A surface relief grating with a period of 30 µm is embossed onto the surface of magnetoactive elastomer (MAE) samples in the presence of a moderate magnetic field of about 180 mT. The grating, which is represented as a set of parallel stripes with two different amplitude reflectivity coefficients, i ...
