Recently I am researching about SELF-HEALING ABILITY; SOYBEAN-OIL; CYCLIC CARBONATES; FREE ROUTES; ELASTOMERS; CHEMISTRY; POLYMERS; RECOVERY; DELIVERY; DIAMINES, Saw an article supported by the National Natural Science Foundation of ChinaNational Natural Science Foundation of China (NSFC) [51873055, 51373046]; Natural Science Foundation of Hebei ProvinceNatural Science Foundation of Hebei Province [B2018202112]; Basic Science Research Program through the National Research Foundation of Korea [2018R1D1A1A09081809]. Published in ROYAL SOC CHEMISTRY in CAMBRIDGE ,Authors: Dong, JC; Liu, BY; Ding, HN; Shi, JB; Liu, N; Dai, B; Kim, I. The CAS is 56-17-7. Through research, I have a further understanding and discovery of 2,2′-Disulfanediyldiethanamine dihydrochloride
A series of isocyanate-free polyurethanes (NIPUs), showing an intrinsic thermo-healing performance, have been synthesized from sustainable vegetable oil-based cyclic carbonates and bio-based amines. The bio-based contents of the NIPUs are higher than 78%. Their thermo-mechanical and self-healing performances are tailored simply by varying the feed ratios of the amines employed. The biomass linoleic acid dimer-based diamine plays a positive role in maintaining the higher thermal stability and good elasticity of the prepared NIPUs, the cycloaliphatic isophorone diamine contributes to high tensile strength, and cysteine-derived disulfide-containing cystamine (CA) enhances the self-healing efficiency. The combination of intrinsic hydrogen bonds existed in the NIPU matrix with the dynamic exchange reactions of disulfide bonds and the enhanced flexibility of NIPU networks results in 98.1% self-healing efficiency at 25 degrees C. The contributions of disulfide bonds and hydrogen bonds to the healing efficiency were estimated by adjusting the composition of NIPUs, showing that the contribution of disulfide bonds to the healing ability is about 45.3% even at a low amount of CA (6.0 wt%).
