Abstract

We investigated polyurethane (PU)-carbon nanotube (CNT) nanocomposites (PU/CNT) in a range of concentrations from 1 to 8 wt% CNT as hot melt adhesives. We studied the thermal properties of the nanocomposites, which is relevant from an applied point of view. The phase angle plots versus complex modulus results revealed the existence of a maximum above a given CNT concentration. The intensity of the peak and associated relaxation time was analyzed with percolation theory, leading to a new method to determine the rheological percolation threshold. A lower threshold value was obtained from the electrical conductivity data, which was justified recalling that the hopping/tunnelling effect takes place in the nanocomposite, as stated by previous studies in the literature. Joule effect studies indicated that the heating effect was very significant, reaching temperature increases, ΔT, of 60 °C for low voltages. For the first time, the percolation equation was applied to the ΔT to obtain the corresponding threshold. Stimulus-responsive systems were conceived considering the correlation between the ΔT and the conductivity. The case of PU/CNT nanocomposites acting as hot melt adhesives that are welded/unglued by applying/removing an electrical voltage is presented.

摘要

我们研究了浓度范围为1至8 wt%碳纳米管（CNT）的聚氨酯（PU）-碳纳米管纳米复合材料（PU/CNT）作为热熔粘合剂的性能。我们研究了纳米复合材料的热性能，这从应用角度来看是相关的。相角图与复数模量结果表明，在给定的CNT浓度以上存在一个最大值。利用渗流理论分析了峰值强度和相关的弛豫时间，从而得出了一种确定流变渗流阈值的新方法。从电导率数据获得了一个较低的阈值，正如文献中先前研究所表明的，纳米复合材料中发生了跳跃/隧穿效应，这证明了该阈值的合理性。焦耳效应研究表明，加热效应非常显著，对于低电压，温度升高ΔT可达60°C。首次将渗流方程应用于ΔT以获得相应的阈值。考虑到ΔT与电导率之间的相关性，构思了刺激响应系统。介绍了PU/CNT纳米复合材料作为热熔粘合剂，通过施加/去除电压进行焊接/解粘的情况。
