论文摘要
我们证明了将散装黑磷大规模剥落成黑色磷。我们使用湿射厂（WJM）作为一种可扩展的去角质技术。为了避免脱落薄片的氧化降解，在剥落过程中，几层黑磷受到功能化的保护（具有4-溴苯二二氮二氮二苯）的保护。我们使用去角质和功能化的薄片作为甲基丙烯酸甲酯基质中的填充剂来测试机械耐力，与裸聚合物相比，年轻模量的改善为106％。这些数据支持黑色磷材料作为2D聚合物填充剂和性能增强剂的发展。
We demonstrate the large scale exfoliation of bulk black phosphorus into few-layers black phosphorus. We use wet-jet mill (WJM) as an industrially scalable exfoliation technique. In order to avoid the degradation by oxidation of the exfoliated flakes, the few-layers black phosphorus is protected by functionalisation (with 4-bromobenzene-diazonium tetrafluoroborate) during the exfoliation process. We used the exfoliated and functionalised flakes as fillers in a polymethyl methacrylate matrix to test the mechanical endurance, obtaining an improvement in the Young modulus of 106% compared to the bare polymer. These data support the development of black phosphorus materials as 2D-polymer fillers and performance-enhancers.
