Patterning Inorganic (CaCO3) Thin Films via a Polymer-Induced Liquid-Precursor Process

摘要: The biomimetic synthesis of patterned mineral thin films, based on a combination the microcontact printing technique and novel crystallization process called polymer-induced liquid-precursor (PILP) process, is demonstrated. PILP enables deposition smooth continuous calcitic films (up to 1500 nm in thickness) under low-temperature aqueous-based processing conditions. are formed by colloidal droplets composed liquid-phase precursor that induced polymeric process-directing agent (polyaspartate or polyacrylate salts). can be preferentially deposited onto substrates templated with self-assembled monolayers (SAMs) alkanethiolate gold. coalesce form an amorphous film, which then transforms (solidifies crystallizes) while retaining shape template, providing means for patterning location morphology two-dimensional calcite crystals.
