以生物高分子卡拉胶水凝胶为连续相，将钛酸钡粒子或钛酸钡/高分子聚合物核壳复合粒子分别在有、无电场的作用下分散于连续相中，得到了几种卡拉胶复合弹性体。通过动态粘弹谱仪测试其储能模量，探讨外加电场对弹性体电场响应性能的影响。结果表明：复合弹性体对外加电场有正响应；分散有高分子聚合物包覆的核壳粒子的弹性体，对外加电场作用的响应优于分散有纯钛酸钡粒子的弹性体。

The carrageenan composite hydrogel elastomers disperesed BaTiO3 particles and BaTiO3/polymer core " shell composite particles were prepared in the presence or absence of an applied dc electric field.To explore the impact of external dc electric field on the carrageenan composite hydrogel elastomers,a series of storage modulus tests on the composite hydrogel elastomers were carried out by a dynamic mechanical analyzer.The results show that the composite elastomers have positive responses to applied electric field.The composite elastomers dispersed by BaTiO3/polymer particles have much more responses than that dispersed by BaTiO3 particles.
