摘要
用聚甲基丙烯酸甲酯 (PMMA)包裹由水玻璃、铝盐和羧酸形成的硅铝氧烷凝胶 ,制备的微囊复合材料用硅油调制成稳定的悬浮液 ,并测试了该悬浮液的电流变效应。结果表明 :这种悬浮液ER效应显著 。
Poly methyl methacrylate (PMMA) was used to wrap alumina siloxane gel which was formed by water glass, aluminum nitrate and α methacrylic acid. Using silicon oil to stir the prepared microcapsule composite material, a kind of stable suspension was produced, and its ER effect was measured. Results showed that the ER effect of this suspension was significant and stable.
