Abstract

Few-layer black phosphorus (BP)- and red phosphorus (RP)-modified diglycidyl ether of bisphenol A-based epoxy resins (EP) was prepared with 4,4'-diaminodiphenylsulfone as a curing agent. The thermal stability and flame-retardant properties of the modified EPs were compared. Both BP and RP were able to improve the flame-retardant properties of EPs, while the BP showed higher flame-retardant efficiency than RP. As a two-dimensional nanomaterial, BP exhibited good compatibility, high flame-retardant efficiency, and negligible impact on the mechanical and thermal stability of EP. Pyrolysis-gas Fourier-transform infrared spectroscopic analysis of EP showed that the addition of BP significantly inhibited the release of pyrolysis products in the gas phase. The modes of action for flame-retardant BPs in gas phase and condensed phase were proposed.

摘要

以4,4'-二氨基二苯砜为固化剂,制备了少层黑磷(BP)和红磷(RP)改性的双酚A基环氧树脂(EP)。比较了改性环氧树脂的热稳定性和阻燃性能。BP和RP均能提高环氧树脂的阻燃性能,而BP的阻燃效率高于RP。作为一种二维纳米材料,BP表现出良好的相容性、高阻燃效率,并且对环氧树脂的机械和热稳定性影响可忽略不计。对环氧树脂进行热解气相傅里叶变换红外光谱分析表明,BP的加入显著抑制了气相中热解产物的释放。提出了阻燃BP在气相和凝聚相中的作用模式。
