Implementation of the self-healing concept in coatings is challenging because they have to combine mech. strength and chain mobility. This challenge is addressed in this work by studying the effect of the polymer microstructure on the mech. properties and self-healing ability of waterborne poly(urethane-urea) coatings containing aromatic disulfide dynamic bonds. The structural modifications studied are the concentration and flexibility of the aromatic disulfide units and the effect of crosslinking. The effects and limits of these structural changes on the mech. properties of the polymers and their healability were determined via a combination of DMA measurements, tensile tests, and rheol. and scratch closure experiments It was found that the flexibility of the disulfide unit was key to develop more efficient self-healing materials which offer the necessary mol. mobility for self-healing while simultaneously maintaining a level of mech. strength that are essential for coating applications. In the experiment, the researchers used 3-Bromopropan-1-ol(cas: 627-18-9Related Products of 627-18-9)
3-Bromopropan-1-ol(cas: 627-18-9) was used in the synthesis of fluorescent halide-sensitive quinolinium dyes and molten salt-polymers. Furthermore, it was used in the synthesis of chiral, quaternary prolines via cyclization of quaternary amino acids.Related Products of 627-18-9
