摘要
This study is focused on making molds with micrometer-sized feature arrays, studying high solids loading nanoparticle suspension for nanoparticle-based templating, and cast forming of surface-templated materials. Polydimethylsiloxane (PDMS) and silicone molds with micrometer-sized feature arrays are made using mold cores templated by a focused ion beam microscope. Al(2)O(3) nanoparticle suspensions are evaluated based on nanoparticle interaction energy and suspension flowability in order to obtain stable and high solids loading suspensions. Templated feature transfer ability is compared for the PDMS and silicon molds under ambient and freeze-drying conditions. This work provides a new approach for surface templating of nanoparticle-based materials.
