摘　　要：合成了聚酰胺酸锂盐和钙盐,并将其分散在硅油中形成电流变体,并对它们在电场作用下的流变性能进行了测试。测试结果表明聚酰胺酸锂盐有明显的电流变效应;而聚酰胺酸钙盐在常温下却呈负电流变效应,在较高的温度下(75℃)才有电流变效应。Studied the synthesis of a lithium salt and calcium salt of polyamic acid, which dispersed in a silicon oil and tested the rheological properties under a electric field. The results showed that the lithium salt of polyamic acid had obvious rheological effect, while the calcium salt of polyamic acid has a negative rheological effect at a room temperature and has rheological effect at elevated temperature (75 ℃).
