Effect of Polymers (PEG and PVP) on Sol-Gel Synthesis of Microsized Zinc Oxide
Figure 2
Schematic of ZnO microparticles capped by polymer molecules: (a) PEG was added to the ZnO solution before synthesis; (b) PEG was added to the ZnO solution after synthesis; (c) PVP was added to the ZnO solution before synthesis; (d) PVP was added to the ZnO solution after synthesis.
