Effect of Carbonyl Iron Powder Content on Mechanical and Magnetic Properties of Porous Magneto-sensitive Elastomer
摘要
Abstract
The high magnetorheological effect and excellent mechanical properties of magneto-sensitive elastomers are the basic guarantee for their use as sensors and actuators.The natural rubber-based porous magneto-sensitive elastomers with excellent mechanical and magnetorheological properties were prepared by chemical foaming method using carbonyl iron powder as magnetic particles.The phase,magnetic properties,microstructure,magnetorheological properties and mechanical properties were tested.The effects of carbonyl iron powder content on magnetorheological properties and mechanical properties were investigated.It was found that the pore morphology of the porous magneto-sensitive elastomer was circular and closed,the content of carbonyl iron powder can effectively adjust the pore size.When the content of carbonyl iron powder was 60 wt%,the mechanical properties of the porous magneto-sensitive elastomer reached the highest.The tensile strength was 4.62 MPa,which was 153.8%higher than the porous magneto-sensitive elastomer without the addition of carbonyl iron powder.The elongation at break reached 300.5%and the magnetorheological properties reached the best,in which the magnetorheological effect was as high as 464.3%.关键词
