Triple-shape memory epoxy (EP)/polycaprolactone (PCL) systems (PCL
content: 23 wt %) with different structures (PCL nanoweb embedded in EP matrix and
EP/PCL with co-continuous phase structure) were produced. To set the two temporary
shapes, the glass transition temperature (Tg) of the EP and the melting temperature (Tm) of
PCL served during the shape memory cycle. An attempt was made to reinforce the PCL
nanoweb by graphene nanoplatelets prior to infiltrating the nanoweb with EP through
vacuum assisted resin transfer molding. Morphology was analyzed by scanning electron
microscopy and Raman spectrometry. Triple-shape memory characteristics were
determined by dynamic mechanical analysis in tension mode. Graphene was supposed to
act also as spacer between the nanofibers, improving the quality of impregnation with EP.
The EP phase related shape memory properties were similar for all systems, while those
belonging to PCL phase depended on the structure. Shape fixity of PCL was better without
than with graphene reinforcement. The best shape memory performance was shown by the
EP/PCL with co-continuous structure. Based on Raman spectrometry results, the
characteristic dimension of the related co-continuous network was below 900 nm
