composite materials often exhibit viscoelastic behavior 粘彈性是材料的重要性質(zhì)。
effective viscoelastic behavior of particulate polymer composites at finite concentration 高體積百分比顆粒增強聚合物材料的有效粘彈性性質(zhì)
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 在蒙脫土含量低至3叭%時,體系低頻率區(qū)域(末端區(qū)域)的動態(tài)模量出現(xiàn)近似于固體的粘彈行為尸類固(solid-li毅的”行為),模量對頻率依賴性降低甚至無依賴性。
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 用高級流變擴展系統(tǒng)(ares)及毛細管流變儀對復合體系熔體的線性粘彈行為、穩(wěn)態(tài)剪切流變行為進行了表征,并對熔體粒子網(wǎng)絡(luò)結(jié)構(gòu)的形成與演化作了較系統(tǒng)的研究。
