Analyzing the Mechanical Properties of Shape Memory Nanocomposites Enhanced by Introducing GnP

Shape memory polymers (SMPs) are capable of enduring significant deformations and returning to their original form upon activation by certain external stimuli. However, their restricted mechanical capabilities have limited their broader application in engineering fields. To address this, the integration of graphene nanoplatelets (GnPs) with SMPs has proven effective in enhancing their mechanical properties while maintaining inherent shape memory functions. The study evaluated shape memory nanocomposites (SMNCs) using static tensile, flexural and shape memory tests, along with scanning electron microscopy to analyze tensile fractures. The findings indicated that the SMNCs achieved their best shape memory and mechanical performance at a GnP concentration of 0.6 wt%.
