Abstract Scope |
The creation of interconnected path architectures, or foams, has become a popular method to prevent agglomeration and enhance the thermal and electrical properties of polymer nanocomposites. Combining such 2D material structures with vitrimers could enable recyclability, repairability, and shape recovery, with potentially accelerated heat response when adding GNP to the structure. This research monitored the shape recovery of neat vitrimer and vitrimer/GNP foam nanocomposites under three heat stimuli: hot water, hot plate, and current application. The addition of GNP increased the shape-recovery rate in all conditions. Hot water provided the highest initial recovery rate but led to incomplete recovery due to quick cooling. Samples on the hot plate fully recovered at a slower rate, while the current method enabled recovery only for the vitrimer nanocomposites. The GNP foam enhances mechanical properties, thermal, and electrical conductivity of polymer nanocomposites, but can also increase shape-recovery rate and enable recovery via current application. |
