Hollow ZnO hemisphere films obtained using colloidal micro-particle templating via self-assembly monolayer |
| 초록 |
Chemical, physical synthesis routes were combined to prepare macroporous ZnO thin films by RF sputtering onto poly methyl methacrylate microsphere templated substrates. No heating was applied to the substrates during ZnO film deposition to prevent decomposition of the PMMA templates. Upon removal of the PMMA template by thermal decomposition during 450℃ calcinations of ZnO, the residual films exhibit a quasi-ordered arrays of hollow ZnO hemisphere with diameter commensurate with that of the original PMMA microspheres. Despite the thermal decomposition of the supporting template during the calcinations step, no adhesion problems and significant shrinkages were observed due to dense ZnO film formation by physical vapor deposition as well as strong chemical bonds between film and substrate formed at 450℃. This unique morphology increased active surface area while reducing the deleterious interfacial effects leading to enhanced surface activity for various electrochemical applications. |
