The information in the text is summarized as follows:
Deformation-controlled solar thermal storage and release are important for thermal management of dynamic systems. However, few researchers have examined cyclic solid-state solar thermal utilization with different deformations. A uniform flexible stretchable solar thermal fuel film is presented using polynorbornene-templated azobenzene (PNB-Azo) with ring-opening metathesis polymerization and covalent grafting. This film has a high degree of isomerization and good storage stability compared to push-pull electronic interaction. At 20% strain rate, the film combines high-degree photocharging (85%), high energy d. (49.0 Wh kg-1), and high rate of heat release induced by blue light (475 nm) at room temperature Greater free volume improves isomerization and the first-order kinetic constant is increased by 1 order of magnitude. Reversible elec.-driven dynamic stretching during charging and discharging enables PNB-Azo””fingers”” to release heat more rapidly than static stretched film, resulting in a temperature increase of 1.5 °C. The result indicates that PNB-Azofilm can be used as a high-power dynamic solar heat source by controlling the deformation. The experimental part of the paper was very detailed, including the reaction process of 6-Aminohexan-1-ol(cas: 4048-33-3SDS of cas: 4048-33-3)
6-Aminohexan-1-ol(cas: 4048-33-3) may be used along with glutaric acid to generate poly(ester amide)s with excellent film- and fiber forming properties. It can undergo cyclization over copper supported on γ-alumina and magnesia to form hexahydro-1H-azepine.SDS of cas: 4048-33-3
