Silicone-Containing Biodegradable Smart Elastomeric Thermoplastic Hyperbranched Polyurethane.

ABSTRACT: Silicone-containing biobased hyperbranched polyurethane thermoplastic elastomers at different compositions were reported for the first time. The structures of the polymers were evaluated from Fourier transform infrared spectroscopy, NMR, X-ray diffraction, and energy-dispersive X-ray spectroscopy analyses. The synthesized elastomers possess high molecular weight (1.11-1.38 × 10⁵ g·mol^-1) and low glass transition temperature (from -40.0 to -27.3 °C). These polymers exhibited multistimuli responsive excellent repeatable intrinsic self-healing (100% efficiency), shape recovery (100%), and efficient self-cleaning (contact angle 102°-107°) abilities along with exceptional elongation at break (2834-3145%), high toughness (123.3-167.8 MJ·m^-3), good impact resistan
