Electroactive Self-Healing Shape Memory Polymer Composites Based on Diels–Alder Chemistry

چکیده
Both shape memory and self-healing polymers have received significant attention from the materials science community. The former, for their application as actuators, self-deployable structures, medical devices; latter, extending lifetime of polymeric products. effects can be stimulated by heat, which makes resistive heating a practical approach to trigger these effects. Here we show conductive polyketone polymer carbon nanotube composite with cross-links based on thermo-reversible furan/maleimide Diels–Alder chemistry. This resulted in products efficient electroactive effect, reprogrammability, self-healing. They exhibit behavior recovery ratios about 0.9; requiring less than minute recovery; able repair microcracks almost fully recover mechanical properties; voltage order tens volts both To best our knowledge, this is first report composites that use covalent reversible linkages, yield robust solvent-resistant networks without jeopardizing reprocessability. These responsive may ideal soft robotics actuators. are also step toward sustainable allowing an increased

Shape-Memory Polymer Composites
The development of shape-memory polymer composites (SMPCs) enables high recovery stress levels as well as novel functions such as electrical conductivity, magnetism, and biofunctionality. In this review chapter the substantial enhancement in mechanical properties of shape-memory polymers (SMPs) by incorporating small amounts of stiff fillers will be highlighted exemplarily for clay and polyhedr...
متن کاملShape Memory Assisted Self-Healing Coating
In this communication, we report the preparation and characterization of new shape memory assisted selfhealing (SMASH) coatings. The coatings feature a phaseseparated morphology with electrospun thermoplastic poly(εcaprolactone) (PCL) fibers randomly distributed in a shape memory epoxy matrix. Mechanical damage to the coating can be self-healed via heating, which simultaneously triggers two eve...
متن کاملSelf-healing of damage in fibre-reinforced polymer-matrix composites.
Self-healing resin systems have been discussed for over a decade and four different technologies had been proposed. However, little work on their application as composite matrices has been published although this was one of the stated aims of the earliest work in the field. This paper reports on the optimization of a solid-state self-healing resin system and its subsequent use as a matrix for h...
متن کاملModeling and Simulation of Magnetic Shape--Memory Polymer Composites
Composites of small magnetic-shape-memory (MSM) particles embedded in a polymer matrix have been proposed as an energy damping mechanism and as actuators. Compared to a single crystal bulk material, the production is simpler and more flexible, as both type of the polymer and geometry of the microstructure can be tuned. Compared to polycrystals, in composites the soft polymer matrix permits the ...
