Paper Abstract

We report on miscible blends comprised of linear-poly(ε-caprolactone) (l-PCL) and chemically crosslinked network- PCL (n-PCL). The blends demonstrate unique Shape Memory Assisted Self-Healing (SMASH) property, which is the materials ability to close local microscopic cracks and heal those cracks by bonding the crack surfaces. For Shape Memory (SM) characterization, temporary deformation of the networks was achieved at room temperature. Samples were temporarily fixed below their crystalline temperature (Tc) and shape recovery was triggered by a temperature above the blends melting temperature (Tm). Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) were used to study the thermal properties of the blends and Dynamic Mechanical Analysis (DMA) and small-scale tensile testing were used to obtain the mechanical properties and self-healing efficiencies of the blends.
