A commercially available aliphatic thermoplastic polyurethane formulated with a methylene bis(cyclohexyl) diisocyanate hard segment and a poly(tetramethylene oxide) soft segment and chain-extended with 1,4-butanediol was dissolved in dimethylformamide and mixed with dispersed single-walled carbon nanotubes. The properties of composites made with unfunctionalized nanotubes were compared with the...

Building upon earlier success in forming materials with crystalline ordering of POSS via the telechelic architecture with POSS end-capping polyethylene glycols, here we report similar ordering in PEG-POSS thermoplastic polyurethane applicable to a novel hybrid hydrogel. Thus, a unique series of hybrid thermoplastic polyurethanes (TPUs) were synthesized using poly(ethylene glycol) (PEG) as soft ...

Wireless-powered VOCs sensors fabricated by combining an energy-harvesting metamaterial and ionic thermoplastic polyurethane operational within microwave frequencies are reported in article number 2001240 Sung-Min Park, Do Hwan Kim, Hojin Lee, co-workers. By harvesting commercially accessible Wi-Fi energy, the sensor can be operated wirelessly, representing a novel method for designing real-tim...

Research in urethane-acrylate UV-curables has shown that these materials have mechanical properties inferior to those of thermoplastic polyurethanes with very similar composition owing to the high cross-link density in UV-curables; in particular, their ultimate extension is low (less than 100%). Past attempts a t increasing the ultimate extension involved compromising the advantages of the UV-c...

Graphene oxide (GO) sheets were dispersed into N, N-dimethylformamide (DMF) solution by ultrasonication and then mixed with thermoplastic polyurethane (TPU) uniformly, further fabricated to GO-TPU film casting process. The thermal properties, infrared photothermal response, self-healing performance of the systematically investigated. experimental results demonstrate that conductivity 4 wt % GO ...

Molecular spin-crossover (SCO) complexes are phase-change materials that develop large spontaneous strains across the thermally induced phase transition, which can be advantageously used in designing soft actuators. Herein, a bilayer bending cantilever, made of thermoplastic polyurethane (TPU) with embedded [Fe(NH2trz)3](SO4) SCO particles (25 wt%), is presented. The proposed actuator fabricate...
