In this study, two series of the polyimide−silica hybrid optical thin films, PMDA−ODA/SiO2 and 6FDA−ODA/SiO2, were synthesized using an in situ sol−gel reaction combined with spin coating and multistep curing. The hybrid thin films were prepared by the aminoalkoxysilane-capped poly(amic acid)s and t...
