摘要

自21世纪初以来，由于对可穿戴设备、软体机器人和智能织物的需求不断增加，柔性电子得到了快速发展。在这种情况下，镓基液态金属(LMs)因其优异的导电性、化学稳定性和生物相容性而在柔性电子领域受到广泛青睐。然而，室温下LMs作为液体难以控制形貌和形状，限制了它的直接利用。将LMs分散到高分子基体中形成液态金属高分子复合材料(LMPCs)，则表现出独特的导热、导电、机械和制备性能。因此，这类新兴的软多功能复合材料在可穿戴设备、可拉伸电子产品、软机器人和超级电容器等现在技术中被广泛应用。为更有效地制备和发展这些独特的复合材料，有必要了解它们的流变行为。本文总结了近年来对LMPCs流变行为的研究进展，主要讨论了不同高分子基体的LMPCs的流变行为对其机械性能和导电性能的影响，并指出该领域所面临的机遇和挑战。

Abstract

Since the beginning of the 21

century

flexible electronics have undergone rapid development due to the increasing demand for wearable devices

soft robots

and smart textiles. In this context

gallium-based liquid metals (LMs) have gained wide popularity in the field of flexible electronics due to their excellent conductivity

chemical stability

and biocompatibility. However

the extremely high surface tension and low viscosity of LMs result in poor adhesion to most substrates

limiting their direct use. The dispersion of LMs in polymer matrices to form liquid metal polymer composites (LMPCs) not only avoids the aforementioned problem but also exhibits unique thermal conductivity

electrical conductivity

and mechanical properties. Consequently

these emerging soft multifunctional composites are widely applied in current technologies such as wearable devices

stretchable electronic products

soft robots

and supercapacitors. To effectively prepare and develop these unique composites

it is necessary to understand their rheological behavior. This article presents a summary of recent research progress on the rheological behavior of LMPCs. The main focus is on the influence of the rheological behaviour of LMPCs with different polymer matrices on their mechanical and electrical conductivity properties. Additionally

this article identifies the opportunities and challenges currently facing this field.
