Abstract：

Epoxy-based　nanocomposites　were　prepared　with　the　addition　of　poly(ethyleneimine)　(PEI,　an　amine-riched　polymer)　functionalized　multi-walled　carbon　nanotubes　(MWCNTs),　whose　microstructure　was　characterized　by　TEM　and　FTIR　spectra.　Effects　of　PEI-functionalized　MWCNTs　(PEI-MWCNTs)　on　micromechanical　properties　of　nanocomposites　were　characterized　by　instrumented　indentation　with　Berkovich　indenter　and　microscratch　test　with　Rockwell　C　indenter.　With　the　increase　in　the　content　of　PEI-MWCNTs:　both　nanoindentation　hardness　and　elastic　modulus　of　nanocomposites　increase;　scratch　normal　hardness　and　elastic　recovery　rate　decrease　in　an　approximately　linear　way;　fracture　toughness　obtained　by　scratch-based　linear　elastic　fracture　mechanics　in-crease　in　an　approximately　linear　way.
