composite materials often exhibit viscoelastic behavior 粘弹性是材料的重要性质。
effective viscoelastic behavior of particulate polymer composites at finite concentration 高体积百分比颗粒增强聚合物材料的有效粘弹性性质
the linear viscoelastic behavior of melts for nanocomposites with different content of montmorillonite modified by cetyltrimethylammonium bromide and octadecyltrimethylammonium bromide was studied . the results obtained through examining the dynamic storage module g ", dynamic loss module g " and stress relaxtion module g ( t ) of the composites revealed that the linear viscoelastic properties of composites strongly depended on the loadings of montmorillonite exfoliated into the composites 在蒙脱土含量低至3叭%时,体系低频率区域(末端区域)的动态模量出现近似于固体的粘弹行为尸类固(solid-li毅的”行为),模量对频率依赖性降低甚至无依赖性。
and the linear viscoelastic behavior, steady rheological behavior and the formation / evolvement of particles net structure for molten nanocomposites were studied using an advanced rheometric expansion system ( ares ) and capillary rheometry . it is believed that the melt intercalation is a more efficient processing for formation of nanophase in polymer-layered silicates hybrids 用高级流变扩展系统(ares)及毛细管流变仪对复合体系熔体的线性粘弹行为、稳态剪切流变行为进行了表征,并对熔体粒子网络结构的形成与演化作了较系统的研究。
