ABSTRACT

In this work we have focussed to examine the effect of carbon black (CB) (3 wt%) and reactive organo-modified montmorillonite R-OMMT (1–3 wt%) on rheological, tensile, thermal, and fracture properties of thermoplastic polyurethane (TPU). XRD curves shows that completely exfoliated structures were obtained using 1 wt% and 2 wt% R-OMMT as a compatibilizer in CB reinforced TPU composites, whereas 3 wt% R-OMMT shows intercalated structures which may be due to agglomeration of clay nanoparticles beyond 2 wt%. Using 2 wt% R-OMMT, essential and nonessential work required for fracture was found to increase by 16.8% and 74%, respectively.

摘要

在这项工作中，我们重点研究了炭黑（CB）（3 wt％）和反应性有机改性蒙脱土R-OMMT（1-3 wt％）对热塑性聚氨酯的流变，拉伸，热和断裂性能的影响（TPU）。XRD曲线表明，在CB增强的TPU复合材料中，使用1 wt％和2 wt％的R-OMMT作为增容剂可获得完全剥离的结构，而3 wt％的R-OMMT显示出插层结构，这可能是由于粘土纳米粒子的团聚度超过2重量％。使用2 wt％的R-OMMT，发现断裂所需的基本工作和非必要工作分别增加了16.8％和74％。
