The star-shaped C60-(styrene)-(sodium p-styrenesulfonate) copolymer [C60-poly(St-SS)] was synthesized successfully.The layer-by-layer self-assembly films from [C60-poly(St-SS)]/diazoresin were fabricated on mica by ionic attractive force.The crosslinking structure formed from the conversion of ionic bond to covalent bond after UV irradiation.The roughness and microtribological property of these films were investigated by AFM/ FFM
which provided insights into the prediction of load-bearing ability on C60-containing films.It was found that the microtribological properties are tightly related with the soft chain length and the layer number of the films.
