摘要

本研究通过对废旧氟橡胶边角料进行高温碳化合成了一种新型含氟碳纳米球，并研究了其与氟橡胶的混合方法。结果发现，与机械混合法相比，溶液混合法使氟橡胶的拉伸强度（7.6%）和 100 % 应变模量（13.3%）最高。此外，添加含氟纳米碳圈可显著增强氟橡胶的耐热性，抑制其热降解，并提高其最终使用温度（266.3 °C，2 年）。这项研究为制备高性能氟橡胶复合材料提供了新的思路。

Preparation of a novel fluoride-containing carbon nanosphere by high-temperature carbonization method for enhancing fluororubber's mechanical and thermal degradation performance

In this study, a novel fluorine-containing carbon nanosphere was synthesized by high-temperature carbonization of waste fluororubber trimmings, and its mixing method with fluororubber was investigated. It was found that the solution mixing method resulted in the highest tensile strength (7.6 %) and modulus at 100 % strain (13.3 %) of fluororubber compared to the mechanical mixing method. Furthermore, the addition of fluorine-containing carbon nanosphere can significantly enhance fluororubber's heat resistance, inhibit its thermal degradation, and increase its ultimate service temperature (266.3 °C, 2 years). This work provides new insights into the preparation of high-performance fluororubber composites.

期刊介绍： Polymer Testing focuses on the testing, analysis and characterization of polymer materials, including both synthetic and natural or biobased polymers. Novel testing methods and the testing of novel polymeric materials in bulk, solution and dispersion is covered. In addition, we welcome the submission of the testing of polymeric materials for a wide range of applications and industrial products as well as nanoscale characterization. The scope includes but is not limited to the following main topics: Novel testing methods and Chemical analysis • mechanical, thermal, electrical, chemical, imaging, spectroscopy, scattering and rheology Physical properties and behaviour of novel polymer systems • nanoscale properties, morphology, transport properties Degradation and recycling of polymeric materials when combined with novel testing or characterization methods • degradation, biodegradation, ageing and fire retardancy Modelling and Simulation work will be only considered when it is linked to new or previously published experimental results.
