Commercial rubber is hardly considered as raw materials to manufacture multifunctional shape‐memory polymers (SMPs) because it is difficult to either tune its glass transition temperature or introduce crystalline domains. Here, we report the manufacture of luminescent SMP composites based on commercial carboxylated nitrile rubber and rare earth organic complex (REOC) with Sm³⁺ ions. The dispersion of REOC and the properties of the composites were investigated in detail. The increase in the REOC loading did not deteriorate the tensile strength and elongation at break of the composites, when the stresses at low strains were highly improved. The strong filler‐chain interaction increased the glass transition temperature of the rubber composites. Besides, luminescent functions were introduced into such rubber composites, while luminescent intensities and lifetime can also be affected by REOC loadings. Finally, the prepared rubber composites presented a light‐induced shape‐memory effect under the irradiation of near‐infrared light due to the photothermal effect of the REOC.

使用稀土有机配合物和商用羧化丁腈橡胶制造发光的形状记忆聚合物复合材料

商业橡胶几乎不被认为是制造多功能形状记忆聚合物（SMP）的原料，因为很难调节其玻璃化转变温度或引入晶畴。在这里，我们报道了基于商业羧化丁腈橡胶和Sm ^3+的稀土有机配合物（REOC）的发光SMP复合材料的制造离子。详细研究了REOC的分散性和复合材料的性能。当高度改善低应变应力时，REOC负载的增加不会降低复合材料的拉伸强度和断裂伸长率。强大的填料链相互作用提高了橡胶复合材料的玻璃化转变温度。此外，发光功能被引入到这种橡胶复合物中，而发光强度和寿命也可能受到REOC负载的影响。最后，由于REOC的光热效应，制备的橡胶复合材料在近红外光的照射下表现出光诱导的形状记忆效应。
