20.500.12556/RUL-155471 Surface modification of magnetoactive elastomers by laser micromachining It has been recently demonstrated that laser micromachining of magnetoactive elastomers is a very convenient method for fabricating dynamic surface microstructures with magnetically tunable properties, such as wettability and surface reflectivity. In this study, we investigate the impact of the micromachining process on the fabricated material’s structural properties and its chemical composition. By employing scanning electron microscopy, we investigate changes in size distribution and spatial arrangement of carbonyl iron microparticles dispersed in the polydimethylsiloxane (PDMS) matrix as a function of laser irradiation. Based on the images obtained by a low vacuum secondary electron detector, we analyze modifications of the surface topography. The results show that most profound modifications occur during the low-exposure (8 J/cm$^2$) treatment of the surface with the laser beam. Our findings provide important insights for developing theoretical models of functional properties of laser-sculptured microstructures from magnetoactive elastomers. magnetoactive elastomers laser micromachining scanning electron microscopy magnetoaktivni elastomeri lasersko mikrostrukturiranje vrstična elektronska mikroskopija true false true Angleški jezik Slovenski jezik Članek v reviji 2024-04-03 16:26:11 2024-04-03 16:26:12 2024-04-04 03:52:40 0000-00-00 00:00:00 2024 0 0 12 str. iss. 7, art. no. 1550 Vol. 17 Mar. 2024 0000-00-00 Zaloznikova NiDoloceno NiDoloceno 0000-00-00 0000-00-00 2024-03-28 620.3 1996-1944 10.3390/ma17071550 191305987 materials-17-01550-v2_(1).pdf materials-17-01550-v2_(1).pdf 1 0F3559D49718AC4563DA08AABF3F9A01 3ebcf19b115ecaa89dc3ce68e9f71e700cfd60105f6c2f6e92772871dd286236 61c202c0-f1c6-11ee-853b-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182379 https://www.mdpi.com/1996-1944/17/7/1550 0 6c52d81d-f1c6-11ee-853b-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182380 Fakulteta za matematiko in fiziko 0 0 0
