完整的论文描述了从废塑料中提取的纳米材料——碳纳米流体，并展示了纳米流体作为油藏条件下提高石油采收率 (EOR) 应用的高效替代纳米剂的潜力。我们开发了一种新颖、可持续、经济高效的方法，通过结合热解、化学功能化和粉碎，以废塑料原料为原料，扩大 Janus 碳纳米粒子 (JC-NPs) 的合成规模，从而实现 JC-NPs 的大规模生产达到工业规模的数量。
最近的研究表明，与均质纳米颗粒流体相比，具有不对称表面特性的纳米颗粒（即 Janus 纳米颗粒）可以以非常低的负载浓度实现更高的石油采收率效率。然而，迄今为止，Janus 纳米粒子的探索和使用面临着重大挑战，阻碍了合成的可扩展性、定制的化学功能化以及引入多种功能的能力。因此，需要工业规模生产Janus纳米材料的新方法。

The complete paper describes nanomaterials—Janus carbon nanofluids—derived from waste plastics and demonstrates the potential of the nanofluids as highly effective alternative nanoagents for enhanced oil recovery (EOR) applications at reservoir conditions. A novel, sustainable, cost-effective method has been developed to scale up synthesis of Janus carbon nanoparticles (JC-NPs) from waste plastic feedstock by combined pyrolysis, chemical functionalization, and pulverization, which allows for production of the JC-NPs in mass quantities at an industrial scale.
Recent research has demonstrated that nanoparticles with asymmetric surface properties (i.e., Janus nanoparticles) could achieve a much higher efficiency of oil recovery factors with very low concentrations of loading compared with homogeneous nanoparticle fluids. To date, however, major challenges facing the exploration and use of Janus nanoparticles exist, impeding scalability of synthesis, tailored chemical functionalization, and the ability to introduce a diverse set of functionalities. Therefore, new methods for production of Janus nanomaterials on an industrial scale are desired.
The authors present a novel technique to convert waste plastic materials into carbon-based nanomaterials for EOR applications.
