摘要

The aim of this study is to develop magnetopolymer composites suitable for fabricating soft magnetoactive robots via extrusion-based 3D printing. Polysiloxane copolymers with urea fragments were synthesized and characterized, and their thermophysical and rheological properties were investigated. This study provides an assessment of the potential for their further use in additive manufacturing. The obtained materials were utilized as matrices for creating magnetically active polymer composites by incorporating microparticles of carbonyl iron. Samples of complex geometries were printed using both neat and filled filaments, demonstrating the feasibility of employing these materials in extrusion-based 3D printing.
