(a) The average value of the loading force applied in three parallel Revetest Scratch tests performed for each sample. Eight organic solvents, aprotic or protic (polarity from 0.01 to 7.2), were adopted to post-treat the freshly fabricated TNTs, with samples washed by H2O as a control. (b) Schematic diagram for interfaces naturally stripping and mechanically stripping. (c) AFM photos of NS face and MS face.
