Herein, we incorporate photosensitive ortho-Nitrobenzyl units into polyurethanes to achieve controllable photodegradability. We performed their photolysis in solution and thin films which can inform the design of degradable adhesives.

Polyurethanes are most often called “green” when they contain natural, renewable additives in their network or chemical structure, such as mono- and polysaccharides, oils (mainly vegetable oils), polyphenols (e.g., lignins, tannins), various compounds derived from agro-waste white biotechnology (Principle 7). This usually results these polyurethanes obtained less hazardous substrates 4). Approp...

The discovery and development of new adhesive materials is critical for real-world applications polymeric composite materials. Herein, we report the design synthesis a library structurally related phase-separated supramolecular polyurethanes whose mechanical properties characteristics can be enhanced through minor structural modifications polymer end-group. interplay between phase separation ha...

Self-healing cementitious materials can extend the service life of structures, improve safety during repair activities and reduce costs with minimal human intervention. Recent advances in self-healing research have shown promise for capsule-based intrinsic healing systems. However, limited information is available regarding vascular-based mechanisms. The aim this work to compare different comme...
