对高填充聚合物熔体的流变行为进行了研究。在接近最大堆积分数的浓度下，在应变低至 1% 时观察到应变依赖性行为。选定的表面处理被证明可以减少颗粒团聚。这样生产出的复合材料熔体具有较低的粘度和较高的最大负载。虽然 η* – ω 图提供了有关颗粒间网络剪切强度的信息，但 G′ – ω 图显示了相分离的证据。
The rheological behavior of highly filled polymer melts has been examined. At concentrations near the maximum packing fraction, strain‐dependent behavior was observed at strains as low as 1 percent. Selected surface treatments were shown to reduce particle agglomeration. This produced composite melts with lower viscosities and higher maximum loadings. While η* – ω plots provide information on the shear strength of the interparticle network,G′ – ω plots show evidence of phase separation.
