Abstract

Geminate thermal stability with optical characteristics is a moving forward achievement in the preparation of polybutadiene-based polyurea nanocomposites. In this regard, nitrogen-doped graphene quantum dots were synthesized from a one-pot hydrothermal reaction of citric acid with urea in an aqueous solution. An in situ polymerization approach was used for the synthesis of polyurea from the reaction of telechelic amine functionalized polybutadiene and toluene diisocyanate (TDI) in the presence of the DBTDL catalyst. Nanocomposites were prepared using 1–3 weight percent of graphene N-quantum dot nanoparticles in the polymer matrix. 1H-NMR and FT-IR spectroscopy techniques elaborated successful synthesis of primary polymer binder, polyurea and nanocomposites. Thermal degradation and characteristics were investigated using the TGA/DTG and DSC methods; lower degradation rates with progressed thermal stabilities as well as proportionate thermal characteristics with wider thermal service range were obtained especially in 3 wt% nanocomposite. Optical behavior information of samples was studied using UV-vis absorption and photoluminescence (PL) spectrometers. EDX, SEM, and AFM techniques confirmed successful nanoparticle and nanocomposite synthesis with improved morphologic and topographic properties.

n掺杂石墨烯量子点纳米粒子利用聚丁二烯链改性合成光学活性热稳定聚脲纳米复合材料
具有光学特性的Gemate热稳定性是制备聚丁二烯基聚脲纳米复合材料的一项前沿成就。在这方面,通过柠檬酸与尿素在水溶液中的一锅水热反应合成了氮掺杂石墨烯量子点。采用原位聚合方法,在DBTDL催化剂存在下,由遥爪胺官能化聚丁二烯和甲苯二异氰酸酯(TDI)反应合成聚脲。纳米复合材料是使用聚合物基体中1-3重量%的石墨烯N量子点纳米颗粒制备的。1H-NMR和FT-IR光谱技术阐述了初级聚合物粘合剂、聚脲和纳米复合材料的成功合成。用TGA/DTG和DSC方法研究了其热降解性能;特别是在3wt%的纳米复合材料中,获得了具有提高的热稳定性的较低降解率以及具有更宽热服务范围的成比例的热特性。利用紫外-可见吸收光谱和光致发光光谱研究了样品的光学行为信息。EDX、SEM和AFM技术证实了纳米颗粒和纳米复合材料的成功合成,并改善了形态和形貌特性。
