| polyurethane-urea containing disulfide (The highly efficient self healing polyurethane-urea containing disulfide bonds (DSPU) was synthesized by using the prepolymer of poly (caprolactone) diol (PCL-diol) with isophorone diisocyanate (IPDI) as the main-chain to achieve good mechanical toughness, then cross-linking with bis(4-aminophenyl) disulfide (APD) to gain the superior reversibility. silver_glepha) | |||
