Bimodal Cell Structure of a Layered Silicate-Thermoplastic Olefin Elastomere Nanocomposite

摘要

Since thermodynamic instability is the driv-ing force for the development of nucleation sites in the cell structures, it is crucial to un-derstand the criteria for creation of Optimum foam features. Recently more and more studies have focused on polymer foaming directly in extrusion process, what is addressed mainly for industrial applica-tions. On the other hand, the value of batch foaming allows better control over the op-erating environment so that one can ob-serve properties in relation to the cellular morphology without processing history playing a role on foaming (ex. observing the impact of chemical super heat without me-chanical super heat) [1].
