Facilely Electrophoretic Derived Aluminum/Zinc (II) Oxide Nanocomposite with superhydrophobicity and thermostability

Developed energetic composites (e.g. aluminum/zinc (II) oxide) with superhydrophobicity and outstanding thermostability destine to be an attractive new generation of energy materials with wide applications. In this work, the superhydrophobic aluminum/zinc (II) oxide coatings (SAZECs) have been designed by electrophoretic deposition (EPD) of components co-scattered in optimal stable suspension of isopropyl alcohol, acetylacetone, and polyethyleneimine as the effect additive, followed by surface energy reducing treatment. Combining energy dispersive X-ray, field emission scanning electron microcopy and X-ray diffraction, we characterized target coatings with relative even distribution and high purity. Wettability analysis results indicated that the SAZECs possessed both high water contact angle (CA) of similar to 168 degrees and severe exothermic property with heat-release up to 1.88 x 10(3) J/g. Moreover, product showed excellent water-proof stability and thermostability after twelve months exposure experiments. This work demonstrates fundamental insights for the superhydrophobic energetic materials enabled by rationally designing electrophoretic co-assembly of charged particles, thus possessing universal significance in improving MICs life time while offering a facile reference to design other self-protected MICs for real industrial application.
