The surface enrichment and phase separation structures of epoxy resin and poly(ε-caprolactone)-block-polydimethylsiloxane-block-poly(ε-caprolactone) triblock copolymer (PCL-b-PDMS-b-PCL) blends were studied using tapping mode atomic force microscopy (TM-AFM) and frictional force microscopy (FFM). Friction and wear properties show that the surface is enriched with the PDMS component and it reaches a stable state at a PCL-b-PDMS-b-PCL mass fraction of about 30%. Contact angle measurements on the surface also support these results.
