增塑剂是一类通过改变材料微观结构而制成的现代材料。与传统材料不同，助剂在拉伸载荷下呈现负泊松比。这些材料由于其增强的性能，如密度、刚度、断裂韧性和阻尼性，在研究界得到了普及。本文提供了一个关键的监督，特别强调了消长泡沫，由于其低廉的价格，容易获得和理想的力学性能。讨论的重点领域包括制造方法，不同参数（温度，加热时间，电池形状和尺寸以及体积压缩比）的影响，微观结构模型，力学性能和潜在的应用。
Auxetics are a modern class of material fabricated by altering the material microstructure. Unlike conventional materials, auxetics exhibit a negative Poisson's ratio when subjected to tensile loading. These materials have gained popularity within the research community because of their enhanced properties, such as density, stiffness, fracture toughness and dampening. This paper provides a critical oversight of the auxetic field with particular emphasis to the auxetic foams, due to their low price, easy availability and desirable mechanical properties. Key areas discussed include the fabrication method, the effects played by different parameters (temperature, heating time, cell shape and size and volumetric compression ratio), microstructural models, mechanical properties and potential applications.
