Block Poly(carbonate?ester) Ionomers as High?Performance and Recyclable Thermoplastic Elastomers

چکیده
Thermoplastic elastomers based on polyesters/carbonates have the potential to maximize recyclability, degradability and renewable resource use. However, they often underperform suffer from familiar trade-off between strength extensibility. Herein, we report well-defined reprocessable poly(ester-b-carbonate-b-ester) with impressive tensile strengths (60 MPa), elasticity (>800 %) recovery (95 %). Plus, ester/carbonate linkages are fully degradable enable chemical recycling. The superior performances attributed three features: (1) Highly entangled soft segments; (2) Fully reversible strain-induced crystallization (3) Precisely placed ZnII-carboxylates dynamically crosslinking hard domains. one-pot synthesis couples controlled cyclic monomer ring-opening polymerization alternating epoxide/anhydride copolymerization. Efficient convresion ionomers is achieved by reacting vinyl-epoxides install ZnII-carboxylates.

متن کاملInjection Molding Micro- and Nanostructures in Thermoplastic Elastomers
Amongst the ever-growing toolbox of microand nanofabrication techniques, polymer replication-based processes continue to attract attention due to the conceptual simplicity, reproducibility, and great variety of often cheap materials that can be used. Cost and time saving advantages are further provided by high throughput replication techniques such as roll-to-roll nanoimprint lithography [ 1 ]
متن کاملMultiphase 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 کاملPreferential Nanoreinforcement of Thermoplastic Polyurethane Elastomers with Dispersed Nano-Clay
It is difficult for scientists to engineer elastomeric materials that are both strong and tough like spider dragline silk. Inspired by the morphology of spider dragline silk and motivated to develop strong, tough, elastomeric polyurethanes to be used in soldier applications I have prepared polyurethane/clay nanocomposites. Polymer/clay nanocomposites have exhibited great potential for providing...
