Incorporating an iodine filler into PEO-BDK-MR thin films enhances the isomerization energy barrier and significantly increases the processing time, making them potential candidates for applications involving molecular solar thermal energy storage media.
We report the effect of an iodine filler on photoisomerization kinetics of photo-switchable PEO-BDK-MR thin films. The kinetics of photoisomerization and time progression of PEO-BDK-MR/I-2 nanocomposite thin films are investigated using UV-Vis, FTIR spectroscopies, and modified mathematical models developed using new analytical methods. Incorporating iodine filler into the PEO-BDK-MR polymeric matrix enhances the isomerization energy barrier and considerably increases the processing time. Our outcomes propose that enhanced photoisomerized and time processed (PEO-BDK-MR)/I-2 thin films could be potential candidates for a variety of applications involving molecular solar thermal energy storage media.
