使用傅里叶红外光谱仪对GO,BTA-GO进行表征，表明GO与BTA能够发生酰胺化反应。样品制备：取适量溴化钾（KBr）研细，加入GO研细均匀，然后倒入压片模具中，压片，制得测试KBr片。取适量KBr颗粒研细均匀，倒入压片模具中，压片，制得空白KBr片，分别滴入稀释100倍的BTA和B-GO乙醇溶液在空白KBr片表面。所有KBr片在测试之前在50 ℃烘箱中保存。

GO and BTA-GO were characterized by Fourier infrared spectrometer, and it was shown that GO and BTA could undergo amidation reaction. Sample preparation: Take an appropriate amount of potassium bromide (KBr) to grind, add GO to grind evenly, and then pour it into the tablet pressing mold to press the tablet to obtain test KBr tablets. Take an appropriate amount of KBr particles to grind evenly, pour them into the tablet pressing mold, press the tablet, and prepare blank KBr tablets. Drop 100-fold diluted BTA and B-GO ethanol solutions on the surface of the blank KBr tablets respectively. All KBr tablets were stored in an oven at 50 ° C before testing.
