Carbon dioxide (CO2) is becoming an increasingly crucial synthetic feedstock for chemicals and polymers, since it is abundant, cheap, and non-toxic. In present study, commercially available polyols from CO2 and polyether polyol were successfully incorporated into thermoplastic polyurethanes (TPUs). The thermal, mechanical, and shape memory properties of the TPUs were compared with those of traditional TPUs from petroleum-based polyether polyol such as poly(tetrahydrofuran). Compared with the petroleum-based polyol TPUs, the CO2-based TPUs exhibited increased glass transition temperature, moduli, and favorable shape memory properties, demonstrating harder and tougher elastomers. In addition, TPUs from CO2-based polyols exhibited enhanced electrochemical corrosion resistance at room temperature compared with that of polyether-based polyol. These findings suggested that CO2-based TPUs are promising alternatives to conventional TPUs. |
