I want to make sure the correct condition about amidation in the graphene oxide , especially the critical temperature. through which I can contrast to other reaction
Its possible.. but you should start with graphene oxide.. follow this strategy (doi:10.1088/0957-4484/20/18/185502; DOI 10.1007/s40089-014-0097-4) and many more.
In my experience, some amide derivatives of carbon nanomaterials can be afforded via simple heating at about 150°C, for example (DOIs):

10.1016/j.apsusc.2012.07.068
10.1166/jnn.2014.9011
10.1016/j.apsusc.2015.09.252
10.1080/1536383X.2016.1188805

273 K seems to be too low temperature for that. With COOH groups, amines would give simple salts under such conditions. But instead, amines could add covalently onto epoxy groups of GO.
