Direct synthesis of carbon quantum dots in aqueous polymer solution: one-pot reaction and preparation of transparent UV-blocking films, J. Mater. Chem. A, 2017,5, 5187-5194
The polymer will not going to degrade because the method protocol follow by author in the article: Synthesis and characterization of quantum dot–polymer composites, J. Mater. Chem., 2009, 19, 3198–3206 ; are as follow:
"QD were also encapsulated into two other commercially available polymers: cyanoacrylate and two-part epoxy. In a typical procedure used in this study, 2 mL of QDs dissolved in a chloroform solution (OD ¼ 0.5) was mixed vigorously with 2 mL of a polymer solution at room temperature. The curing of the composites was performed at room temperature for several hours "
So since curing of composite was perform at room temperature there will be no chance for degradation of polymer.
