AbstractCTS-0098132Michael Mackay, Stevens Institute of TechnologyIn a set of preliminary experiments, the PI was able to blend low concentration nanoscale particles in linear chain polymer of the same species. Remarkably, the rheology of this blended material is altered in such a way that its viscosity and modulus are reduced. This effect will have potential favorable impact on procession of polymers. The aim of the present proposal is to determine the mechanism by which the viscosity and the modulus are reduced by a set of planned experiments.

摘要CTS-0098132 Michael Mackay，Stevens Institute of Technology在一组初步实验中，PI能够将低浓度的纳米级颗粒混合在相同种类的线性链聚合物中。 值得注意的是，这种共混材料的流变性以降低其粘度和模量的方式改变。 这种效应对聚合物的加工具有潜在的有利影响。 本提案的目的是通过一组计划的实验来确定粘度和模量降低的机制。
