20.500.12556/RUL-152367 Dynamically tunable lamellar surface structures from magnetoactive elastomers driven by a uniform magnetic field Stimuli responsive materials are key ingredients for any application that requires dynamically tunable or on-demand responses. In this work we report experimental and theoretical investigation of magnetic-field driven modifications of soft-magnetic elastomers whose surface was processed by laser ablation into lamellar microstructures that can be manipulated by a uniform magnetic field. We present a minimal hybrid model that elucidates the associated deflection process of the lamellae and explains the lamellar structure frustration in terms of dipolar magnetic forces arising from the neighbouring lamellae. We experimentally determine the magnitude of the deflection as a function of magnetic flux density and explore the dynamic response of lamellae to fast changes in a magnetic field. A relationship between the deflection of lamellae and modifications of the optical reflectance of the lamellar structures is resolved. magnetoactive elastomers laser micro-machining lamellar structures magnetoaktivni elastomeri lasersko mikrostrukturiranje lamelne strukture true false true Angleški jezik Slovenski jezik Članek v reviji 2023-11-22 14:59:35 2023-11-22 14:59:36 2023-11-23 03:39:05 0000-00-00 00:00:00 2023 0 0 Str. 3357-3365 iss. 18 Vol. 19 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 539.2 1744-683X 10.1039/d3sm00012e 149684995 d3sm00012e.pdf d3sm00012e.pdf 1 A093875523C51D1D4A47662DFBC48A76 e7e684ee08143e62ace9f6c7490b2b6f4104c7272f9cf504e81bbdb0013069f0 9134bbb1-893f-11ee-916c-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=177853 https://pubs.rsc.org/en/content/articlelanding/2023/SM/D3SM00012E 0 7972f498-893f-11ee-916c-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=177852 Fakulteta za matematiko in fiziko Fakulteta za strojništvo 0 0 0
