can-1332	Zhao, Aiming; Dong, Yanmao; Ni, Qiuyang; Bao, Zhiyu	Synthesis and application of nano-MH/MPB as intumescent flame retardant (IFR)	2021	9	.pdf	application/pdf	4285	224	65	In Figure 2c, there are not only the O-H stretching absorption peak 3,702 cm–1 in MH structure, but also the over- lapping 3,339 cm–1 and 3,132 cm–1 of N-H stretching vibration absorption peaks in -NH3+, -OH and -NH2 in MPB structure, P=O stretching vibration absorp- tion peak 1,265 cm–1, C=N stretching vibration ab- sorption peak 1,656 cm–1. These groups can form hydrogen bonds with -OH of nano MH (as shown in Figure 1).	cache/can-1332.pdf	txt/can-1332.txt
