Abstract
Infiltration synthesis, the atomic-layer-deposition-based organic-inorganic material hybridization technique that enables unique hybrid composites with improved material properties and inorganic nanostructures replicated from polymer templates, is shown to be driven by the binding reaction between reactive chemical groups of polymers and perfusing vapor-phase material precursors. Here, we discover that residual solvent molecules from polymer processing can react with infiltrating material precursors enabling the infiltration synthesis of metal oxides in a non-reactive polymer. The systematic study, combining in-situ quartz crystal microgravimetry, polarization-modulated infrared reflection-absorption spectroscopy, X-ray photoelectron spectroscopy, and transmission electron microscopy, shows that the ZnO infiltration synthesis in nominally non-reactive SU-8 polymer is mediated by residual processing solvent cyclopentanone, a cyclic ketone whose Lewis-basic terminal carbonyl group can react with the infiltrating Lewis-acidic Zn precursor diethylzinc (DEZ). In addition, we find favorable roles of residual epoxy rings in the SU-8 film in further assisting the infiltration synthesis of ZnO. The discovered rationale not only improves the understanding of infiltration synthesis mechanism but also potentially expands its application to more diverse polymer systems for the generation of unique functional organic-inorganic hybrids and inorganic nanostructures. | 43 pages
