Abstract

In this work, a general, facile, and relatively low-cost method to produce electrically driven non-porous membranes by revalorization of recycled polyolefins is proposed. The polymer matrices are poly(propylene) (PP) and poly(ethylene) (PE) and their corresponding recycled samples, which are respectively mixed with carbon nanotubes (CNT). The performances of the elaborated nanocomposites are studied by morphological, rheological, and electrical conductivity tests. The Joule heating effect is evaluated by applying an electric field and recording the corresponding temperature rise. An increase of 90 °C is obtained in certain cases, which represents the highest temperature enhancement reached so far by the Joule effect in thermoplastics, to our knowledge. The work shows a route to develop stimulus (voltage)-response (temperature) materials with low cost and with potential applications in many fields. As an example, the increase of the permeability with temperature of membranes made of the indicated nanocomposites, is analyzed.

摘要

在这项工作中，提出了一种通过回收聚烯烃的再利用来制备电驱动无孔膜的通用、简便且成本相对较低的方法。聚合物基体是聚丙烯（PP）和聚乙烯（PE）及其相应的回收样品，它们分别与碳纳米管（CNT）混合。通过形态学、流变学和电导率测试研究了所制备的纳米复合材料的性能。通过施加电场并记录相应的温度升高来评估焦耳热效应。在某些情况下，温度升高可达90℃，据我们所知，这是迄今为止热塑性塑料中焦耳效应所达到的最高温度升高。这项工作展示了一条开发低成本且在许多领域具有潜在应用的刺激（电压）-响应（温度）材料的途径。例如，分析了由上述纳米复合材料制成的膜的渗透率随温度的变化。
