The effect of several mixing process parameters on the concentration of carbon black particles at the interface between the polymer components in polyethylene–polystyrene mixtures was studied. It was established that the process of particle transport from the polymer phase to the interface happens only under the action of shear deformation, but simultaneously acting shear stresses prevent particle concentration. The nanoparticle accumulation at the interface is determined not only by how favored this process is thermodynamically, but also by the parameters of the mixing process. The filler concentration at the interface is facilitated by a reduction in the shear stress, polymer viscosity, filler particle size, and preliminary injection of filler into the polymer component that is less effective at wetting the filler surface. © 2019 Wiley Periodicals, Inc.

聚苯乙烯-聚乙烯混合物中界面处固体纳米颗粒浓缩的动力学方面

研究了几种混合工艺参数对聚乙烯-聚苯乙烯混合物中聚合物组分之间界面处炭黑颗粒浓度的影响。已经确定，颗粒从聚合物相到界面的传输过程仅在剪切变形的作用下发生，但是同时作用的剪切应力会阻止颗粒集中。纳米颗粒在界面处的聚集不仅取决于该过程在热力学上的有利程度，还取决于混合过程的参数。通过减小剪切应力，聚合物粘度，填料颗粒尺寸以及将填料预注入聚合物组分中，这在润湿填料表面方面不太有效，从而促进了界面处的填料浓度。分级为4 +©2019 Wiley Periodicals，Inc.J.Appl。Polym。科学2020，137，48585。
