Ultrasound-Assisted Hydroxyapatite-Decorated Breath-Figure Polymer-Derived Ceramic Coatings for Ti6Al4V Substrates.

ABSTRACT: The introduction of nanoparticles (NPs) into the breath-figure-templated self-assembly (BFTSA) process is an increasingly common method to selectively decorate a surface porous structure. In the field of prosthetic devices, besides controlling the morphology and roughness of the structure, NPs can enhance the osteointegration mechanism because of their specific ion release. Among the most widely used NPs, there are silica and hydroxyapatite (HAp). In this work, we propose a novel one-stage method to fabricate NP-decorated surface porous structures that are suitable for prosthetic coating applications. This technique combines the classical direct BFTSA process with the cavitation effect induced by an ultrasonic atomizer that generates a mist of water droplets with embedded NPs. Coatings wer
