I am working on making graphene oxide (GO) hydrophobic by attaching hydrophobic chains to its functional groups using a Steglich esterification reaction. I experimented with various ratios of reagents in this process. After washing the GO with DMF, methanol, acetone, and finally deionized water, I observed that one of the samples became completely separated from the water phase during the deionized water wash. Can this observation indicate that the sample successfully became hydrophobic while others did not react as effectively?

This observation may indicate that the sample has successfully become hydrophobic. But to confirm, you can measure the partition coefficient between octyl alcohol and water. Then you can compare your sample with others in terms of hydrophobicity.
