“…Saponite, a member of the smectite family, is 2 : 1 layered clay that consists of one sheet of octahedra between two sheets of silicon tetrahedra. 9) The clay is characterized by its ion (e.g., cation) exchange capacity. An important significance of the charged nature of the clays is that they are generally highly hydrophilic and incompatible with polymers.…”

In the present work, transparent flexible polymer-doped clay (P-clay) substrates were successfully prepared for flexible hybrid organic–inorganic light emitting diode (HyLED) applications. The thermogravimetric–differential thermal analysis (TG–DTA) curves showed that the thermal resistance of P-clay film was higher than that of plastic substrates. Then indium doped tin oxide (ITO) thin films were prepared on newly fabricated P-clay substrates by ion-beam sputter deposition (IBSD) method. The as-prepared ITO/P-clay samples were annealed at 220 °C for 1 h. The optical transparency and electrical conductivity of annealed ITO film on P-clay with smooth surface were better than that of P-clay with rough surface. ZnO seed layers were prepared on annealed ITO/P-clay, ITO/glass, and clay substrates by IBSD method. Surface morphology study showed that the ZnO seed layer coated ITO/P-clay substrate with smooth surface was very suitable for growing vertically aligned ZnO nanorod arrays. The structural study showed that the ZnO nanorod arrays grown by low-temperature solution growth method have good crystallinity and high purity. Optical study showed that the as-prepared ZnO nanorod arrays have excellent optical properties.
