To alleviate the pressure on the petrochemical industry and address environmental concerns,the utilization of polyurethane(PU)derived from castor oil(CO)(as an ester polyol replacement of petrochemicalbased materials)has garnered significant attention in recent *** the service life of materials requires imparting self-healing properties to vegetable oil-based polymers,an aspect that has received limited attention in current ***,low self-healing efficiency still poses a significant challenge,and non-conductivity also remains an obstacle in current research,crucial for their application in electronic *** this work,we present the first series of electrically self-healing biopolymer composites constructed by incorporating carbon nanotube(CNT)networks into crosslinked castor oil-based polyurethane(BPU)through a simple curing *** materials address the challenges mentioned above and exhibit improved mechanical,electrical,and self-healing capabilities compared to other biobased self-healing *** resulting BPU/CNT composite demonstrated exceptional repeated selfhealing capacity,restoring both mechanical properties and electrical performance even after experiencing severe mechanical ***,this composite served as a conductive substrate in flexible solid-state supercapacitor(FSSC)***,the FSSC derived from the composite conductive substrate achieved an impressive 92.4%self-healing efficiency even after undergoing 7 cutting/healing *** device remained virtually unchanged even after being bent at a 180°angle with a bending radius of 1.6 mm,indicating excellent repeatability and *** exceptional self-healing ability,with∼98%electrical recovery at 100℃for 70 s and 93%at 80℃after 6 min,of these composites was attributed to the synergistic interactions of the dynamic exchange reactions of disulfide bonds and dense hydrogen bonds within the BPU matrix,which provide a reversible dynamic polym
