| Abstract Scope |
Magnetic elastomers are a promising approach for artificial muscles and soft robotic systems due to their ability to enable rapid and wireless actuation under external magnetic fields. In this study, an ultra-low modulus photopolymer resin was investigated as a matrix combined with strontium ferrite (SF) particles [SrO(Fe2O3)6]. Composites were fabricated using stereolithography (SLA) with magnetic field-assisted alignment utilizing a Halbach cylinder, enabling control over particle orientation and the formation of anisotropic magnetic properties. Samples were produced with varying SF loadings (1 – 8 wt.%), and magnetic properties were measured using a biaxial vibrating sample magnetometer (VSM). Curing the elastomer composite without a magnetic field resulted in agglomeration without any microstructural alignment of particles as observed with scanning electron microscopy (SEM). However, upon applying a magnetic field, particles aligned in chain-like agglomerates. This work modeled relationships between particle alignment, composition, and composite performance and demonstrated the potential for magnetically actuated applications. |
