Fabrication of the Finestructured TiO2 Ceramic Materials by replication

Abstract

TiO2 porous material with fine-patterned over multiple length scales were prepared by combining replication technique, poly vinyl alcohol (PVA), TiO2 nanosize particles. Our study is based on the idea that PVA can be easily detached from a quartz mold by peeling. The respective ordered structures can be independently modified by choosing different quartz mold patterns. We confirmed that micron and sub-micron-sized fine-structured TiO2 patterns containing nanosized pores could be fabricated using this procedure. The results presented demonstrate the compositional and structural diversities that are possible with a facile approach and simple method.
