چکیده
Abstract Self-healing materials can increase the lifetime of products and improve their sustainability. However, detection damage in an early stage is essential to avoid progression ensure a successful self-healing process. In this study, sensor composite strips were developed with embedding thermoplastic styrene-based co-polymer (TPS) matrix. Piezoresistive TPS fibers composites (SFCs) 3D printed element (SECs) fabricated embedded matrix by lamination process detect damage. both cases, value initial resistance was used presence monitor efficiency healing. A higher elongation at fracture could be achieved extruded fibers. for SECs achieve fracture. Mechano-electrical analysis revealed that maintained monotonic, reproducible response after healing The SFCs had significantly lower drift signal during cyclic mechanical analysis. Nevertheless, on tendon-based soft robotic actuator, obtained below 1%. This explained deformation (e.g.) strain comparison tensile test experiments.

Multiphase design of autonomic self-healing thermoplastic elastomers.
The development of polymers that can spontaneously repair themselves after mechanical damage would significantly improve the safety, lifetime, energy efficiency and environmental impact of man-made materials. Most approaches to self-healing materials require the input of external energy, healing agents, solvent or plasticizer. Despite intense research in this area, the synthesis of a stiff mate...
متن کاملSupramolecular thermoplastics and thermoplastic elastomer materials with self-healing ability based on oligomeric charged triblock copolymers
Supramolecular polymeric materials constitute a unique class of materials held together by non-covalent interactions. These dynamic supramolecular interactions can provide unique properties such as a strong decrease in viscosity upon relatively mild heating, as well as self-healing ability. In this study we demonstrate the unique mechanical properties of phase-separated electrostatic supramolec...

متن کاملDamping Behavior of the Phenolic Based Composite Friction Materials Containing Thermoplastic Elastomers (TPEs)
Attempts have been made for the first time to produce a friction material with thermal sensitive modulus by the inclusion of combined plastic/rubber properties of thermoplastic elastomers (TPE) as viscoelastic polymeric materials into the formulation for the purpose of increasing the damping behavior. In order to evaluate the viscoelastic parameters such as loss factor (tan δ) and elastic m...
