Abstract With the implementation of “plastic restriction order” and demand for sustainable society development, biodegradable coatings derived from biomass materials have garnered significant interest. This study presents synthesis a double‐salt bio‐based waterborne polyurethane (PLA‐WPU) by utilizing poly(lactic acid) polyol (PLA) isophorone diisocyanate (IPDI) as main raw materials, along with 2,2‐dihydroxymethylpropionic acid (DMPA) sodium ethylenediamine ethanesulfonate (A‐95) hydrophilic chain extender. Synergistic reinforcement PLA‐WPU using hydrophobically modified cellulose nanocrystals (M‐CNC) polycarbonate diimide (PDCDA). At an M‐CNC content 3% relative to effective mass PLA‐WPU, tensile strength reached 36.12 MPa. After 8 days lipase PBS solution, degradation rate 54%. Excellent waterproof performance was observed, exhibiting contact angle 143.5°. When applied surface coating on kraft paper, Cobb 60 value decreased 74.0 28.6 g/m 2 , while increasing 451.3%. Importantly, paper maintained excellent waterproofing, mechanical strength, high barrier properties even after repeated folding, low‐temperature conditions, exposure varying pH solutions. It proved be both degradable recyclable, making it promising alternative liner or plastic membrane, especially in food packaging.

Rubber tires are fundamental components of modern society and industrial operations, holding an irreplaceable position in the global manufacturing transportation sectors. The potential for traditional rubber to enhance performance is gradually approaching its limits, rendering it challenging further improve low rolling resistance, high wet-skid wear resistance (called “magic triangle”). Moreover, reliance on petroleum resources hinders sustainable development tires. In this work, a series novel polyurethane (PU) elastomers with applications high-performance automotive were synthesized by CO2-based poly(propylene carbonate) diol bio-based oxide) glycol (PO3G). comprehensive influences PO3G thermal, mechanical, properties systematically investigated. results illustrated that increasing content significantly enhanced 98.43% 73.21% reduced 15.38% compared commercial green (HT166). rational design strategy PU not only effectively addresses triangle” challenge tire industry but leverages CO2 contribute sector.
