“…Composites also showed an increment of the temperature corresponding to the maximum degradation rate ( Table 2 ). These encouraging results about the improved thermal stability of the PS/PMMA blend agree with previous data indicating that fl-bP inhibits mass transfer and provides thermal insulation to shield the underlying polymer from the heat source [ 26 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ]. Similar results have also been reported for other types of ultrathin 2D nanomaterials dispersed both in thermoplastic and thermosetting polymers [ 62 , 63 , 64 ].…”

“…Recently, it has also been shown that bP can improve both the mechanical properties and flame retardancy of epoxy resins [ 32 , 33 ]. Advances have been achieved through functionalization of bP by adsorption of organic molecules [ 34 ] or surface coordination of metal ligands [ 35 , 36 ]. For example, bP was coordinated with a ruthenium sulfonate and a lanthanide metal ligand, respectively, achieving excellent stability in ambient conditions and common solvents, and increasing the dispersibility in epoxy resin.…”

Exfoliated black phosphorus (bP) embedded into a polymer is preserved from oxidation, is stable to air, light, and humidity, and can be further processed into devices without degrading its properties. Most of the examples of exfoliated bP/polymer composites involve a single polymer matrix. Herein, we report the preparation of biphasic polystyrene/poly(methyl methacrylate) (50/50 wt.%) composites containing few-layer black phosphorus (fl-bP) (0.6–1 wt.%) produced by sonicated-assisted liquid-phase exfoliation. Micro-Raman spectroscopy confirmed the integrity of fl-bP, while scanning electron microscopy evidenced the influence of fl-bP into the coalescence of polymeric phases. Furthermore, the topography of thin films analyzed by atomic force microscopy confirmed the effect of fl-bP into the PS dewetting, and the selective PS etching of thin films revealed the presence of fl-bP flakes. Finally, a block copolymer/fl-bP composite (1.2 wt.%) was prepared via in situ reversible addition–fragmentation chain transfer (RAFT) polymerization by sonication-assisted exfoliation of bP into styrene. For this sample, 31P solid-state NMR and Raman spectroscopy confirmed an excellent preservation of bP structure.

Chemical Functionalization of 2D Black Phosphorus toward Its Applications in Energy Devices and Catalysis: A Review

et al. 2021

Due to its unique in‐plane anisotropic structure, high carrier mobility, and adjustable direct bandgap, 2D black phosphorus (BP) has emerged as an important graphene‐like material for various micro‐ and optoelectronic, energy, catalytic, and biomedical applications. However, its lack of environmental stability severely limits its processing in ambient conditions. Chemical functionalization is an effective method for increasing the ambient stability of the material. Herein, the main approaches for chemical functionalization of 2D BP with various organic and inorganic substrates, as well as the routes for the preparation of 0D/2D and 2D/2D heterostructures, are discussed. Furthermore, the recent advances of 2D BP‐based materials in energy and catalysis fields are summarized. Finally, the challenges and future prospects for the preparation and functionalization of 2D BP are also highlighted.

“…1,2 Epoxy resins (EP) with good moisture resistance, dimensional stability, electrical and mechanical properties have become one of the strong candidate materials in semiconductor, printed circuit plate and other electronic materials. [3][4][5] Generally, cross-linked epoxy thermosets were formed by the reaction of oxirane rings with curing agents, such as diamines, 6 phenol novolac, 7 and thiols. 8 In the case, any secondary alcohol linkages were generated after crosslinking, which could render high polarity, high moisture absorption and hydrophilic properties.…”

Benzene-1,3,5-triyl tribenzoate (TBB), both 3,5-bis(benzoyloxy)benzoate-terminated poly (aryl ether ketone) oligomers (BPAPK and TMPK), containing active ester (Ph−O−(C=O)− structure), were prepared and served as curing agents for dicyclopentadiene novoalc epoxy (DCPD). The curing kinetics and properties of three epoxy thermosets were systematically investigated. The model reaction of TBB and glycidyl phenyl ether was designed to understand the curing mechanism of oxirane ring with active ester. TMPK/DCPD displays the lowest reaction activation energy, which is the result of the combined influence of free volume and diffusion. In addition, TMPK/DCPD has the highest Tg value (218°C), which enhances 34.6% and 42.5% compared with BPAPK/DCPD and TBB/DCPD, respectively. Meanwhile, TMPK/DCPD also shows superior dielectric and water resistance properties due to no secondary alcohol generated after curing and hydrophobic tetramethyl-substituted biphenyl structure. Herein, TMPK/DCPD as high-performance epoxy thermosets has potential applications in electronic packaging fields.
