Key Points

To evaluate the impact of diol symmetry on the properties and degradability of bio-based aromatic polyesters.
Utilized bio-based aromatic polyesters with varying diol symmetry.
Conducted enzymatic degradation tests using Thc_Cut1 cutinase at 50 °C over 120 days.
Compared performance metrics to standard PET.
BHB-PD1.0 showed 35.5% weight loss under enzymatic conditions; BHB-HD1.0 showed 30.8% weight loss.
Weight loss rates were 4-fold higher than PET, which had less than 2%.
Demonstrated that diol symmetry can be tuned for enhanced properties and biodegradability.

Abstract

nm <10%), significantly surpassing PET. Under enzymatic conditions with ThcCut1 cutinase (50 °C, 120 days), BHB-PD1. 0 and BHB-HD1. 0 achieved 35. 5% and 30. 8% weight loss, respectively, 4-fold higher than PET (<2%). This symmetry-controlled strategy offers a versatile pathway for next-generation sustainable polymers.
