| Abstract Scope |
Here, we demonstrate a facile temperature-enhanced liquid-phase infiltration (LPI) method to control and drastically increase the quantity and kinetics of Pt infiltration into self-assembled block copolymer (BCP) thin films. By applying LPI at mildly elevated temperatures (40–80 °C), we showcase controllable optical functionality of hybrid BCP films along with conductive three-dimensional (3D) inorganic nanostructures. Quantitative analysis revealed enhanced metal loading into the BCP matrix at higher LPI temperatures. Combining temperature-enhanced LPI with hierarchical multilayer BCP self-assembly, we generated BCP-metal hybrid optical coatings featuring stack-layer-number-dependent antireflective properties as well as 3D Pt nanomesh structures displaying 3D percolating electrical conductance. This work not only enables tunability of organic-inorganic hybrid nanostructures and properties but also expands the library of materials that can be infiltration synthesized, paving a way for synthesizing BCP-templated, unique functional hybrid and inorganic nanostructures for applications in photochemical sensing, energy conversion, and storage. |
