Poly(tartaric acid) is a relatively recently described polymer that can be easily synthesized and scaled up from a readily available renewable material (tartaric acid). This article demonstrates its use in a green synthesis of gold nanoparticles, silver nanoparticles, copper particles, and magnetite nanoparticles. In this case poly(tartaric acid) acts both as a reductant and as a coating agent. To our knowledge this is the first green synthesis of several different types of nanoparticles using only one reagent (polytartrate) as both reductant and coating. The resulting particles were analyzed by XRD, TEM/SEM, EDX, FTIR, DLS, zeta-potential, XPS, and UV/VIS spectroscopy. Preliminary studies of the thermal behavior of mixtures of different types of particles with poly(tartaric acid) were also conducted. The obtained particles show different sizes depending on the material, and the coating allows for better dispersibility as well as potential further functionalization, making them potentially useful also for other applications, besides the inclusion in polymer composites.
聚酒石酸是一种相对较新描述的聚合物，它可以很容易地从一种易于获得的可再生材料（酒石酸）合成并扩大规模。本文展示了其在金纳米颗粒、银纳米颗粒、铜颗粒和磁铁矿纳米颗粒的绿色合成中的应用。在这种情况下，聚酒石酸既作为还原剂又作为包覆剂。据我们所知，这是首次仅使用一种试剂（聚酒石酸盐）作为还原剂和包覆剂对几种不同类型的纳米颗粒进行绿色合成。通过XRD、TEM/SEM、EDX、FTIR、DLS、zeta电位、XPS和UV/VIS光谱对所得颗粒进行了分析。还对不同类型颗粒与聚酒石酸的混合物的热行为进行了初步研究。所获得的颗粒根据材料不同呈现出不同的尺寸，并且这种包覆使得颗粒具有更好的分散性以及潜在的进一步功能化，这使得它们除了用于聚合物复合材料中外，在其他应用中也可能有用。
